After researching digital currencies for work last year, personal finance writer J.R.
Duren hopped on his own crypto-rollercoaster.
Duren bought $5 worth of litecoin in November, and eventually purchased $400 more, mostly with his credit card. In just a few months, he experienced a rally, a crash and a recovery, with the adrenaline highs and lows that come along.
“At first, I was freaking out,” Duren said about watching his portfolio plunge 40 percent at one point. “The precipitous drop came as a shock.”
The 39-year-old Floridian is part of the new class of crypto-investors who do not necessarily think bitcoin will replace the U.S. dollar, or that blockchain will revolutionize modern finance or that dentists should have their own currency.
Dubbed by longtime crypto-investors as “the noobs” — online lingo for “newbies” — they are ordinary investors hopping onto the latest trend, often with little understanding of how cryptocurrencies work or why they exist.
“There has been a big shift in the type of investors we have seen in crypto over the past year,” said Angela Walch, a fellow at the UCL Centre for Blockchain Technologies. “It’s shifted from a small group of techies to average Joes. I overhear conversations about cryptocurrencies everywhere, in coffee shops and airports.”
Walch and other experts cited parallels to the late-1990s, when retail investors jumped into stocks like Pets.com, a short-lived online seller of pet supplies, only to watch their wealth evaporate when the dot-com bubble burst.
Bitcoin is the best-known virtual currency but there are now more than 1,500 to choose from, according to market data website CoinMarketCap, ranging from popular coins like ether and ripple to obscure coins like dentacoin, the one intended for dentists.
Exactly how many “noobs” bought into the craze last year is unclear because each transaction is pseudonymous, meaning it is linked to a unique digital address, and few exchanges collect or share detailed information about their users.
A variety of consumer-friendly websites have made investing much easier, and online forums are now filled with posts from ordinary retail investors who were rarely spotted on the cryptocurrency pages of social news hub Reddit before.
Reuters interviewed eight people who recently made their first foray into digital currency investing. Many were motivated by a fear of missing out on profits during what seemed like a never-ending rally last year.
One bitcoin was worth almost $20,000 in December, up around 1,900 percent from the start of 2017. As of Friday afternoon it was worth about $10,000 after having fallen as much as 70 percent from its peak. Other coins made even bigger gains and experienced equally dizzying drops over that time frame.
“There was that two-month period last year where all the virtual currencies kept going and up and I had a couple of friends that had invested and they had made five-figure returns,” said Michael Brown, a research analyst in New Jersey, who said he bought around $1,000 worth of ether in December.
“I got swept by the media frenzy,” he said. “You never hear stories of people losing money.”
In the weeks after Brown invested, his holdings soared as much as 75 percent and tumbled as much as 59 percent.
Buy and ‘Hodl’
Investors who got into bitcoin before its 2013 crash like to refer to themselves as “OGs,” short for “original gangsters.”
They tend to shrug off the recent downturn, arguing that cryptocurrencies will be worth much more in the future.
“As crashes go, this is one of the biggest,” said Xavier Levenfiche, who first invested in cryptocurrencies in 2011.
“But, in the grand scheme of things, it’s a hiccup on the road to greatness.”
Spooked by the sudden fall but not willing to book a loss, many investors are embracing a mantra known as “HODL.” The term stems from a misspelled post on an online forum during the cryptocurrency crash in 2013, when a user wrote he was “hodling” his bitcoin, instead of “holding.”
Mike Gnitecki, for instance, bought one bitcoin at around $18,000 in December and was sitting on a 43 percent decline as of Friday, waiting for a recovery.
“I view it as having been a fun side investment similar to a gamble,” said Gnitecki, a paramedic from Texas. “Clearly I lost some money on this particular gamble.”
Duren, the personal finance writer, is also holding onto his litecoin for now, though he regrets having spent $33 on credit card and exchange fees for a $405 investment.
Some retail investors who went big into cryptocurrencies for the first time during the rally last year remain positive.
Didi Taihuttu announced in October that he and his family had sold everything they owned — including their business, home, cars and toys — to move to a “digital nomad” camp in Thailand.
In an interview, Taihuttu said he has no regrets. The crypto-day-trader’s portfolio is in the black, and he predicts one bitcoin will be worth between $30,000 and $50,000 by year-end.
His backup plan is to write a book and perhaps make a movie about his family’s experience.
“We are not it in it to become bitcoin millionaires,” Taihuttu said.

The majority of people believe cardiopulmonary resuscitation (CPR) is successful more often than it tends to be in reality, according to a small U.S. study.
This overly optimistic view, which may partly stem from seeing happy outcomes in television medical dramas, can get in the way of decision-making and frank conversations about end of life care with doctors, the research team writes in American Journal of Emergency Medicine.
CPR is intended to restart a heart that has stopped beating, known as cardiac arrest, which is typically caused by an electrical disturbance in the heart muscle. Although a heart attack is not the same thing — it occurs when blood flow to the heart is partly or completely blocked, often by a clot — a heart attack can also cause the heart to stop beating.
Odds of surviving
Whatever the cause of cardiac arrest, restarting the heart as quickly as possible to get blood flowing to the brain is essential to preventing permanent brain damage. More often than not, cardiac arrest ends in death or severe neurological impairment.
The overall rate of survival that leads to hospital discharge for someone who experiences cardiac arrest is about 10.6 percent, the study authors note. But most participants in the study estimated it at more than 75 percent.
“The majority of patients and non-medical personnel have very unrealistic expectations about the success of CPR as well as the quality of life after patients are revived,” said lead author Lindsey Ouellette, a research assistant at Michigan State University’s College of Human Medicine in Grand Rapids.
Patients and family members should know about the realistic success rate and survival numbers when planning a living will and considering a “Do Not Resuscitate” order, Ouellette said.
“We think it is best to have the latest and most accurate information when dealing with this life-impacting decision, whether or not to undertake or continue CPR,” she told Reuters Health in an email.
Good TV, not good information
To gauge perceptions of CPR, the researchers surveyed 1,000 adults at four academic medical centers in Michigan, Illinois and California. Participants included non-critically ill patients and families of patients, who were interviewed during random hospital shifts.
In addition to asking about general knowledge of CPR and personal experiences with CPR, the researchers presented participants with several scenarios and asked them to estimate the likelihood of CPR success and patient survival in each case.
One scenario involved a 54-year-old who suffered a heart attack at home and required CPR by paramedics. About 72 percent of the survey participants predicted survival and 65 percent predicted a complete neurological recovery.
In a scenario describing a trauma-related cardiac arrest in an 8-year-old, 71 percent predicted CPR success and 64 percent predicted long-term survival of the child.
“Many people felt if a person was successfully revived, they would return to ‘normal’ rather than possibly needing lifelong care,” Ouellette said.
At the same time, more than 70 percent of respondents said they watched TV medical dramas regularly, and 12 percent said these shows were a reliable source of health information.
“Tempering unrealistic expectations may not make for ‘good TV,’ but perhaps we can get a better idea of just how these dramas may impact the views people hold about CPR and other aspects of medicine,” she said.
Medical act, not miracle
“People think about CPR as a miracle, but it’s another medical act,” said Dr. Juan Ruiz-Garcia of Hospital Universitario de Torrejon in Madrid who wasn’t involved in the study. “I’m not really sure what people would choose if they knew the real prognosis of it,” he told Reuters Health by phone.
CPR should be part of the conversation about end-of-life care and advanced directives among families, said Carolyn Bradley of Yale-New Haven Hospital in Connecticut.
“When doing CPR at a hospital, we tend to move the family away, but we’ve created a situation where families may not be there for the final moments,” she said in a phone interview.
“Have a critical conversation with your health care provider and go with questions about what would happen during CPR,” she said. “What does it look like? What happens to my body? Who will be around? It could be the end-of-life. Statistically, it is.”

President Emmanuel Macron on Saturday faced heckles and whistles from French farmers angry with reforms to their sector, as he arrived for France’s annual agricultural fair.
For over 12 hours, Macron listened and responded to critics’ rebukes and questions — only to return home to the Elysee Palace with an adopted hen.
“I saw people 500 meters away, whistling at me,” Macron said, referring to a group of cereal growers protesting against a planned European Union free-trade pact with a South American bloc, and against the clampdown on weedkiller glyphosate.
“I broke with the plan and with the rules and headed straight to them, and they stopped whistling,” he told reporters.
“No one will be left without a solution,” he said.
Macron was seeking to appease farmers who believe they have no alternative to the widely used herbicide, which environmental activists say probably causes cancer.
Mercosur warning
He also wanted to calm fears after France’s biggest farm union warned Friday that more than 20,000 farms could go bankrupt if the deal with the Mercosur trade bloc (Brazil, which is the world’s top exporter of beef, plus Argentina, Uruguay and Paraguay) goes ahead.
Meanwhile, Macron was under pressure over a plan to allow the wolf population in the French countryside to grow, if only marginally.
“If you want me to commit to reinforce the means of protection … I will do that,” he responded.
And he called on farmers to accept a decision on minimum price rules for European farmers, “or else the market will decide for us.”
But it wasn’t all jeers and snarls for Macron at the fair.
He left the fairground with a red hen in his arms, a gift from a poultry farm owner.
“I’ll take it. We’ll just have to find a way to protect it from the dog,” he said, referring to his Labrador, Nemo.
It was a far cry from last year, when, as a presidential candidate not yet in office, Macron was hit on the head by an egg launched by a protester.

Investor Warren Buffett says Wall Street’s lust for deals has prompted CEOs to act like oversexed teenagers and overpay for acquisitions, so it has been hard to find deals for Berkshire Hathaway.
In his annual letter to shareholders Saturday, Buffett mixed investment advice with details of how Berkshire’s many businesses performed. Buffett blamed his recent acquisition drought on ambitious CEOs who have been encouraged to take on debt to finance pricey deals.
“If Wall Street analysts or board members urge that brand of CEO to consider possible acquisitions, it’s a bit like telling your ripening teenager to be sure to have a normal sex life,” Buffett said.
Berkshire is also facing more competition for acquisitions from private equity firms and other companies such as privately held Koch Industries.
Sticking with guideline
Buffett is sitting on $116 billion of cash and bonds because he’s struggled to find acquisitions at sensible prices. And Buffett is unwilling to load up on debt to finance deals at current prices.
“We will stick with our simple guideline: The less the prudence with which others conduct their affairs, the greater the prudence with which we must conduct our own,” Buffett wrote.
He said the conglomerate recorded a $29 billion paper gain because of the tax reforms Congress passed late last year. That helped it generate $44.9 billion profit last year, up from $24.1 billion the previous year.
Investors left wanting
Buffett’s letter is always well-read in the business world because of his remarkable track record over more than five decades and his talent for explaining complicated subjects in plain language. But this year’s letter left some investors wanting more because he didn’t say much about Berkshire’s succession plan, some noteworthy investment moves or the company’s new partnership with Amazon and JP Morgan Chase to reduce health care costs.
Edward Jones analyst Jim Shanahan said he expected Buffett to devote more of the letter to explaining his decision to promote and name the top two candidates to eventually succeed him as Berkshire’s CEO. Buffett briefly mentioned that move in two paragraphs at the very end of his letter.
That surprised John Fox, chief investment officer at FAM Funds, which holds Berkshire stock.
“He didn’t say a lot about succession. I was expecting more,” Fox said.
Greg Abel and Ajit Jain joined Berkshire’s board in January and took on additional responsibilities. Jain will now oversee all of the conglomerate’s insurance businesses while Abel will oversee all of the conglomerate’s non-insurance business operations.
Bet pays off for charity
Buffett, 87, has long had a succession plan in place for Berkshire to ensure the future of the conglomerate he built even though he has no plans to retire. Until January, he kept the names of Berkshire’s internal CEO candidates secret although investors who follow Berkshire had long included Jain and Abel on their short lists.
Shanahan said it also would have been nice to read Buffett’s thoughts on why he is selling off Berkshire’s IBM investment but maintaining big stakes in Wells Fargo and US Bancorp.
But Buffett did offer some sage investment advice based on his victory in a 10-year bet he made with a group of hedge funds. The S&P 500 index fund Buffett backed generated an 8.5 percent average annual gain and easily outpaced the hedge funds. One of Buffett’s favorite charities, Girls Inc. of Omaha, received $2.2 million as a result of the bet.
Buffett said it’s important for people to invest money regularly regardless of the market’s ups and downs, but watch out for investment fees, which will eat away at returns.
Succeeding in the stock market requires the discipline to act sensibly when markets do crazy things. Buffett said investors need “an ability to both disregard mob fears or enthusiasms and to focus on a few simple fundamentals. A willingness to look unimaginative for a sustained period — or even to look foolish — is also essential.”
Buffett said investors shouldn’t assume that bonds are less risky than stocks. At times, bonds are riskier than stocks.
Berkshire owns more than 90 subsidiaries, including clothing, furniture and jewelry firms. It also has major investments in such companies as Coca-Cola Co. and Wells Fargo & Co.

Australia appears to be failing in its efforts to crack down on bribery, according to the latest survey conducted by Transparency International, a non-governmental organization based in Germany.
The group said developed countries – including Australia – appeared to be lagging in their efforts to combat corruption in the public sector. It pointed to an inadequate regulation of foreign political donations in Australia, conflicts of interest in planning approvals, revolving doors and improper industry lobbying in large-scale mining projects.
While Australia’s ranking is unchanged – it remains ranked 13th out of 180 countries – its corruption score has slipped eight points since the index started in its current form in 2012.
Concern about Australia’s ranking comes as debate continues about the need for a nationwide anti-corruption body similar to the Independent Commission Against Corruption in the state of New South Wales. It was set up in 1989 and has scored many notable victories, including the jailing of corrupt state politicians.
Professor A.J. Brown, who leads a project called “Strengthening Australia’s National Integrity System” for Transparency International, says much more work needs to be done.
“We do not have a federal anti-corruption body amongst other things, so it is also about the fact that our track record in terms of government commitment to controlling foreign bribery or money laundering and some of the things that the private sector is also involved in internationally is not that strong. We are moving but we have been moving very slow and very late, and not very comprehensively,” Brown said.
This year, New Zealand and Denmark were ranked highest in the Transparency International survey, the U.S. is ranked 16th, while South Sudan and Somalia were the lowest-ranked nations. The best performing region was Western Europe, while the most corrupt regions were Sub-Saharan Africa, followed by Eastern Europe and Central Asia.
The survey found that more than 6 billion people live in countries that are corrupt. Transparency International said most countries failed to protect the independence of the media, which plays a crucial role in preventing corruption.
Three more companies say they have ended marketing programs with the National Rifle Association (NRA), as gun control advocates stepped up pressure on firms to cut ties to the gun industry following last week’s school shooting in Florida.
Activists have posted petitions online, identifying businesses that offer discounts to NRA members, in a push to pressure the companies to cut ties to the gun rights organization.
Corporations that ended their discount programs with NRA members on Friday included insurance company MetLife, car rental company Hertz, and Symantec Corp., the software company that makes Norton Antivirus technology.
The move comes after several other companies cut their ties to the NRA earlier this week, including car rental company Enterprise, First National Bank of Omaha, Wyndham Hotels and Best Western hotels.
The NRA is one of the country’s most powerful lobbying groups for gun rights and claims 5 million members.
Florida shooting renews debate
Last week’s shooting at a Florida high school that left 17 people dead has renewed the national debate about gun control.
Gun control activists have been mounting a campaign on Twitter, including using the hashtag #BoycottNRA as well as using social media to pressure streaming platforms, including Amazon, to drop the online video channel NRATV, which features gun-friendly programming produced by the NRA.
On Thursday, NRA Executive Vice President Wayne LaPierre told the Conservative Political Action Conference (CPAC) that those advocating for stricter gun control are exploiting the Florida shooting.
Receiving a rousing reception, LaPierre said, “There is no greater personal individual freedom than the right to keep and bear arms, the right to protect yourself and the right to survive.”
Arming teachers
On Friday, President Donald Trump reiterated to CPAC for the third time this week the need to arm teachers with concealed weapons to prevent more shootings in U.S. schools.
“It’s time to make our schools a much harder target for attackers. We don’t want them in our schools,” Trump said.
Trump has also proposed raising the age to buy assault-style rifles from 18 to 21, which is opposed by the NRA.
In his speech to CPAC, Trump indicated he does not intend to battle the powerful organization.
“They’re friends of mine,” Trump said of the NRA, which gave more than $11 million to his presidential campaign in 2016 and spent nearly $20 million attacking his Democratic Party general election challenger, Hillary Clinton.
The mass shooting in Florida on Feb. 14 has sparked a wave of rallies in Florida, Washington and in other areas of the United States in an attempt to force local and national leaders to take action to prevent such attacks.
There is no clear and easy way to tell when a person’s thinking process has peaked, but most scientists agree that intelligence starts slowly deteriorating somewhere around age 70.

Some diabetics with plaque buildup in their arteries might have less debris in these blood vessels after adding wine to their diets, a recent study suggests.
For the study, researchers examined data on 224 people with type 2 diabetes who normally didn’t drink alcohol, but were randomly assigned to follow a Mediterranean diet and drink approximately one glass of red wine, white wine or water for daily. Among the subset of 174 people with ultrasound images of their arteries, 45 percent had detectable plaque at the start of the study.
Two years later, researchers didn’t see any significant increase in plaque for any of the participants with ultrasounds, regardless of whether they drank wine or water.
However, among the people who started out with the most plaque in their arteries, there was a small but statistically meaningful reduction in these deposits by the end of the study, researchers report in the European Journal of Clinical Nutrition.
“Among patients with well-controlled diabetes and a low risk for alcohol abuse, initiating moderate alcohol consumption in the context of a healthy diet is apparently safe and may modestly reduce cardiometabolic risk,” said lead study author Rachel Golan, a public health researcher at Ben-Gurion University of the Negev in Beer Sheva, Israel.
“Our study is not a call for all patients with type 2 diabetes to start drinking,” Golan said by email.
Cardio-metabolic risk factors can increase the chances of having diabetes, heart disease or a stroke. In addition to plaque in the arteries, other risk factors include high blood pressure, elevated blood sugar, high cholesterol, smoking and having poor diet and exercise habits.
Previous research
Some previous research has linked drinking moderate amounts of wine or other alcohol to a lower risk of cardiovascular disease in otherwise healthy people as well as diabetics.
In the current study, all of the participants had the most common form of the disease, known as type 2 diabetes, which is linked to obesity and aging and occurs when the body can no longer produce or use the hormone insulin to convert sugars in the blood into energy.
Participants were part of a larger study looking at people with cardiovascular disease and diabetes.
They were typically in their late 50s or early 60s and most of them were overweight or obese. Roughly 65 to 70 percent of them took medications to lower cholesterol or other blood fats and the majority of them also took diabetes drugs to control blood sugar.
Mediterranean diet
Patients were told to follow a Mediterranean diet, which typically includes lots of fruits, vegetables, whole grains, legumes and olive oil. This diet also tends to favor lean sources of protein like chicken or fish over red meat, which contains more saturated fat.
Participants were provided with wine or mineral water throughout the study period along with a 150-milliliter (5.07-ounce) glass to measure their daily dose of their assigned beverage, which was consumed with dinner.
Some previous research has linked a Mediterranean diet to weight loss and a reduced risk of heart disease and some cancers as well as better management of blood sugar in people with diabetes.
One limitation of the current study is the potential for the apparent beneficial effect of the wine to have been at least partially caused by the Mediterranean diet.
Another drawback is that researchers only had ultrasound images of plaque buildup for a small proportion of patients, and the two-year follow up period might not be long enough to detect meaningful differences in plaque accumulation.
There is a risk
Alcohol may help, but it also isn’t risk free, noted Dr. Gregory Marcus, a researcher at the University of California, San Francisco, who wasn’t involved in the study. It can increase the risk of heart rhythm problems, which can cause stroke, Marcus said by email.
Even though alcohol might help reduce the risk of cardiovascular disease in some circumstances, there isn’t enough evidence yet to suggest that people who avoid alcohol should start drinking, Marcus said.
“I would certainly recommend against starting to drink alcohol in the hopes of obtaining beneficial health effects among anyone that currently abstains,” Marcus said. “And among those who drink, these sorts of positive results should never be used to consume more alcohol, particularly beyond drinking in moderation.”
The heaviest, the largest, the most impactful — those were the superlatives the Trump administration used to describe its latest sanctions against North Korea.
But were the Treasury Department designations of more than 50 companies and ships accused of illicit trading with the pariah nation really the toughest action yet by the U.S. and the wider world?
Probably not.
Here’s a look at how President Donald Trump and a top lieutenant described Friday’s sanctions to punish the North for its development of nuclear weapons and ballistic missiles — and how they stack up against past economic restrictions that have been piled on Kim Jong Un’s government in response to its illegal weapons tests.
Treasury Secretary Steven Mnuchin: “The Treasury Department is announcing the largest set of sanctions ever imposed in connection with North Korea.”
Trump: “I do want to say, because people have asked, North Korea — we imposed today the heaviest sanctions ever imposed on a country before.”
As for Trump’s blanket assertion, in sheer dollar terms, the U.S. has actually imposed much costlier restrictions on countries such as Iran, a far richer economy than North Korea’s. Washington and its allies cut off tens of billions of dollars’ worth of Iranian oil exports and shut the country’s central bank out of the international financial system, among other steps, before eliminating those restrictions under a 2015 nuclear deal.
Correct on number
In terms of the number of entities targeted Friday, Mnuchin is probably correct about the history of sanctions on North Korea.
The department blacklisted “one individual, 27 entities and 28 vessels” located, registered or flagged in North Korea, China, Singapore, Taiwan, Hong Kong, Marshall Islands, Tanzania, Panama and Comoros. That appeared to be the most companies or individuals designated by the U.S. at a single time. According to Mnuchin, there are now more than 450 U.S. sanctions against North Korea, about half of them levied in the last year.
But in purely economic terms, both Mnuchin and Trump are well wide of the mark.
The latest designations are primarily intended to crack down on North Korea’s evasion of wider-ranging sanctions adopted by the U.N. Security Council and the United States that are more economically significant.
Over the past year, the council has adopted three sets of sanctions banning North Korean exports of coal, iron ore, textiles, seafood products and other goods. If those measures are properly implemented, that would reduce the North’s export revenues by 90 percent from 2016 levels, or by $2.3 billion annually. Those sanctions are also heavily restricting North Korean fuel supplies. They capped refined oil imports at 500,000 barrels a year. That’s a reduction from the 4.5 million barrels North Korea imported in 2016.
It’s because of those draconian restrictions that North Korea wants to conduct trade on the quiet with “ship-to-ship” transfers that the U.S. is determined to stop. With Friday’s measures, Mnuchin said, the U.S. has gone after “virtually all their ships that they’re using at this moment.”
That’s certainly a significant increase in pressure on North Korea as its foreign trade diminishes. But the Treasury Department did not give an overall figure for how much revenue the North would be deprived of because of the latest actions, other than to say that nine of the newly blacklisted foreign vessels “are capable of carrying over $5.5 million worth of coal at a time.”
‘Underwhelming’ in scope
The conservative-leaning Heritage Foundation did not think much of the new steps.
“As impressive as the list is in length, it is underwhelming in its scope and fails to live up to the hype,” it said. “Like his predecessors, President Trump remains reluctant to go after Chinese financial entities aiding North Korea’s prohibited nuclear and missile programs.”
China is said to account for about 90 percent of North Korea’s external trade and be its main access point to the international financial system. Past U.S. sanctions that have targeted Chinese companies have probably had a much bigger impact on North Korea’s revenue streams.
In November, the Treasury Department blacklisted three Chinese companies that it said had “cumulatively exported approximately $650 million worth of goods to North Korea and cumulatively imported more than $100 million worth of goods from North Korea.”
An even bigger Chinese trading partner of the North was blacklisted in September 2016: Dandong Hongxiang Industrial Development Co. According to a report by the U.S.-based research group C4AD and South Korea’s Asan Institute for Policy Studies, Hongxiang carried out imports and exports worth a total of $532 million in 2011-15. It had also supplied aluminum oxide and other materials that can be used in processing nuclear bomb fuel.

Federal Reserve policymakers fretted on Friday that they could face the next U.S. recession with virtually the same arsenal of policies used in the last downturn and, with interest rates still relatively low, those will not pack the same punch.
In the midst of an unprecedented leadership transition, Fed officials are publicly debating whether to scrap their approach to inflation targeting, how much of its bond portfolio to retain, and how much longer they can raise interest rates in the face of an unexpectedly large boost from tax cuts and government spending.
After years of near-zero rates and $3.5 trillion in bond purchases all meant to stimulate the economy in the wake of the 2007-09 recession, the Fed has gradually tightened policy since late 2015. Its key rate is now in the range of 1.25 to 1.5 percent, and while the Fed plans to hike three more times this
year it has also forecast that it is about halfway to its goal.
That could leave little room to provide stimulus when the world’s largest economy, which is heating up, eventually turns around.
“We would be better off, rather than thinking about what we would do next time when we hit zero, making sure that we don’t get back there. We just don’t want to be there,” Boston Fed President Eric Rosengren told a conference of economists and the majority of his colleagues at the central bank.
Rosengren, one of only a few sitting policymakers who also served during the last downturn, said the expanding U.S. deficits could further erode the government’s ability to help curb any future recession. “With the deficits we are running up, it’s not likely [fiscal policy] will be helpful in the next
recession either,” he said.
Since mid-December, the Republican-controlled Congress and U.S. President Donald Trump aggressively cut taxes and boosted spending limits, two fiscal moves that are expected to push the annual budget deficit above $1 trillion next year and expand the $20 trillion national debt.
Overheating
That stimulus, combined with synchronized global growth, signs of U.S. inflation perking up, and unemployment near a 17-year low could set the stage for overheating that ends one of the longest economic expansions ever.
“We want more shock absorbers out there and really … the main shock absorber is the ability to reduce the fed funds rate, which means that you want to get to a higher inflation rate so that the pre-shock fed funds rate is 4 and not 2,” said Paul Krugman, the Nobel Prize-winning economist and professor at City University of New York.
In a speech to the conference hosted by the University of Chicago Booth School of Business, Krugman said every recession since 1982 has been caused by “private sector over-reach” and not Fed tightening, as in decades past.
The conference’s main research paper argued the central bank should focus on cutting rates in the next recession and avoid relying on asset purchases that are less effective in stimulating investment and growth than previously thought.
In October the Fed began trimming some of its assets and it has yet to decide how far it will go. William Dudley, president of the New York Fed, told the conference that, to be sure, the ability to again purchase bonds if and when rates hit zero “seems like a good tool to have.”
The Fed’s approach to any economic slowdown would likely be to cut rates, pledge further stimulus, and only then buy bonds.
Rosengren and others dismissed the possibility of adopting negative interest rates, as some other central banks have done.
Yet five years of below-target inflation, combined with an aging population and slowdown in labor force growth, has sparked a debate over ditching a long-standing 2 percent price target.
Some see this month’s succession of Fed Chair Janet Yellen by Jerome Powell as ideal timing to consider new frameworks that could help drive inflation, and rates, higher. Cleveland Fed President Loretta Mester, whom the White House is considering for Fed vice chair, told the conference the central bank could begin to reassess the framework later this year, though she added that the threshold for change should be high.

European Union leaders staked out opening positions Friday for a battle over EU budgets that many conceded they are unlikely to resolve before Britain leaves next year, blowing a hole in Brussels’ finances.
At a summit to launch discussion on the size and shape of a seven-year budget package to run from 2021, ex-communist states urged wealthier neighbors to plug a nearly 10 percent annual revenue gap being left by Britain, while the Dutch led a group of small, rich countries refusing to chip in any more to the EU.
Germany and France, the biggest economies and the bloc’s driving duo as Britain prepares to leave in March 2019, renewed offers to increase their own contributions, though both set out conditions for that, including new priorities and less waste.
Underlining that a divide between east and west runs deeper than money, French President Emmanuel Macron criticized what he said were poor countries abusing EU funds designed to narrow the gap in living standards after the Cold War to shore up their own popularity while ignoring EU values on civil rights or to undercut Western economies by slashing tax and labor rules.
Noting the history of EU “cohesion” and other funding for poor regions as a tool of economic “convergence,” Macron told reporters: “I will reject a European budget which is used to finance divergence, on tax, on labor or on values.”
Poland and Hungary, heavyweights among the ex-communist states which joined the EU this century, are run by right-wing governments at daggers drawn with Brussels over their efforts to influence courts, media and other independent institutions.
The European Commission, the executive which will propose a detailed budget in May, has said it will aim to satisfy calls for “conditionality” that will link getting some EU funding to meeting treaty commitments on democratic standards such as properly functioning courts able to settle economic disputes.
But its president, Jean-Claude Juncker, warned on Friday against deepening “the rift between east and west” and some in the poorer nations see complaints about authoritarian tendencies as a convenient excuse to avoid paying in more to Brussels.
At around 140 billion euros ($170 billion) a year, the EU budget represents about 1 percent of economic output in the bloc or some 2 percent of public spending, but for all that it remains one of the bloodiest subjects of debate for members.
Focus on payments
The Commission has suggested that the next package should be increased by about 10 percent, but there was little sign Friday that the governments with cash are willing to pay that.
“When the UK leaves the EU, then that part of the budget should drop out,” said Dutch Prime Minister Mark Rutte, who leads a group of hawks including Sweden, Denmark and Austria.
“In any case, we do not want our contribution to rise and we want modernization,” he added, saying that meant reconsidering the EU’s major spending on agriculture and regional cohesion in order to do more in defense, research and controlling migration.
On the other side, Czech Prime Minister Andrej Babis said his priorities were “sufficient financing of cohesion policy” a good deal for businesses from the EU’s agricultural subsidies.
German Chancellor Angela Merkel said there had been broad agreement that new priorities such as in defense, migration and research should get new funding and she called for a “debureaucratization” of traditional EU spending programs.
Summit chair Donald Tusk praised the 27 leaders — Prime Minister Theresa May was not invited as Britain will have left before the new budget round starts — for approaching the issue “with open minds, rather than red lines.” But despite them all wanting to speed up the process, a deal this year was unlikely.
Quick deal unlikely
Although all agree it would be good to avoid a repeat of the 11th-hour wrangling ahead of the 2014-20 package, many sounded doubtful of a quick deal even early next year.
“It could go on for ages,” Rutte said. He added that it would be “nice” to finish by the May 2019 EU election: “But that’s very tight.”
Among the touchiest subjects will be accounting for the mass arrival of asylum-seekers in recent years. Aggrieved that some eastern states refuse to take in mainly Muslim migrants, some in the west have suggested penalizing them via the EU budget.
Merkel has proposed that regions which are taking in and trying to integrate refugees should have that rewarded in the allocation of EU funding — a less obviously penal approach but one which she had to defend on Friday against criticism in the east. It was not meant as a threat, the chancellor insisted.
In other business at a summit which reached no formal legal conclusions, leaders broadly agreed on some issues relating to next year’s elections to the European Parliament and to the accompanying appointment of a new Commission for five years.
They pushed back against efforts, notably from lawmakers, to limit their choice of nominee to succeed Juncker to a candidate who leads one of the pan-EU parties in the May 2019 vote. They approved Parliament’s plan to reallocate some British seats and to cut others altogether and also, barring Hungary, agreed to a Macron proposal to launch “consultations” with their citizens this year on what they want from the EU.

U.S. stocks rallied on Friday, lifted by gains in technology stocks and a retreat in Treasury yields as the Federal Reserve eased concerns about the path of interest rate hikes this year.
The U.S. central bank, looking past the recent stock market sell-off and inflation concerns, said it expected economic growth to remain steady and saw no serious risks on the horizon that might pause its planned pace of rate hikes.
Investors largely expect the Fed to raise rates three times this year, beginning with its next meeting in March, the first under new Chair Jerome Powell. Traders currently see a 95.5 percent chance of a quarter-percentage-point hike next month, according to Thomson Reuters data.
“Certainly bond yields pulling back today is helpful for stocks, at least for the short term, that has been the narrative that is out there — that higher bond yields are weighing on stocks and this preoccupation with three percent,” said Willie Delwiche, investment strategist at Baird in Milwaukee. “So moving away from that, for today at least, provides a bid for equities.”
Powell’s first public outing will be on Tuesday, when he will testify separately before the House and Senate committees.
The Dow Jones Industrial Average rose 347.51 points, or 1.39 percent, to 25,309.99, the S&P 500 gained 43.34 points, or 1.60 percent, to 2,747.30 and the Nasdaq Composite added 127.30 points, or 1.77 percent, to 7,337.39.
Benchmark 10-year U.S. Treasury notes last rose 13/32 in price to yield 2.8714 percent, from 2.917 percent late on Thursday.
The dip in yields helped boost bond proxy sectors such as utilities, up 2.66 percent, and real estate, up 1.72 percent. The sectors have been among the worst performers so far this year on expectations of climbing rates.
Tech shares climbed 2.17 percent led by gains in Hewlett Packard Enterprise, which rose 10.5 percent and HP Inc, up 3.5 percent.
The two companies created from the split of Hewlett Packard Co in 2015, reported strong results and HPE also announced a plan to return $7 billion to shareholders.
For the week, the Dow rose 0.37 percent, the S&P advanced 0.56 percent and the Nasdaq gained 1.35 percent.
Blue Buffalo Pet Products jumped 17.23 percent after General Mills said it would buy the natural pet food maker for $8 billion. General Mills was the biggest percentage decline on S&P 500, falling 3.59 percent.
Advancing issues outnumbered declining ones on the NYSE by a 4.54-to-1 ratio; on Nasdaq, a 2.82-to-1 ratio favored advancers.
The S&P 500 posted 10 new 52-week highs and one new low; the Nasdaq Composite recorded 64 new highs and 57 new lows.
Volume on U.S. exchanges was 6.05 billion shares, well below the 8.38 billion average over the last 20 trading days.

Leaders of Afghanistan, Turkmenistan, Pakistan and its arch rival India jointly inaugurated construction work Friday on the Afghan section of a long-delayed multibillion-dollar gas pipeline connecting the four nations, raising hopes for regional cooperation and peace.
A ceremony took place in the ancient Afghan city of Herat, attended by President Ashraf Ghani, his Turkmen counterpart, Gurbanguly Berdymukhamedov, Pakistani Prime Minister Shahid Khaqan Abbasi and Indian External Affairs Minister M.J. Akbar.
The long-awaited 1,814 kilometer pipeline, known as TAPI, will transport natural gas from the world’s fourth-largest reserves in Turkmenistan through Afghanistan to growing economies of Pakistan and India, which are facing energy shortages.
TAPI was originally conceived in the 1990s, but differences over terms and conditions, unending Afghan hostilities and regional rivalries are blamed for delays. Turkmenistan took the initiative in December 2015 and has since constructed its portion of the pipeline up to the Afghan border.
President Ghani, while addressing Friday’s ceremony, vowed Afghanistan believes in connectivity and will “not spare any efforts” to implement the project to connect South Asia with Central Asia after a century of separation.
“This is the beginning of confidence in Afghanistan, confidence on national unity and harmony of the state and the people of Afghanistan,” noted Ghani.
Pakistani Prime Minister Abbasi reiterated his country’s commitment to peace and stability in Afghanistan.
“We are turning, by the grace of God, TAPI into a reality. It will provide shared regional prosperity … and it will provide peace dividends,” said Abbasi, whose country is accused of covertly supporting the Afghan Taliban, charges Islamabad denies as baseless.
“I want to tell my Afghan brothers and sisters that your success is our success, your development is our development and peace in Afghanistan means peace in Pakistan,” Abbasi emphasized.
He termed TAPI critical for Pakistan’s energy needs, saying it will provide about 10 percent of his country’s total energy consumption.
Expected cost
Officials say the project, estimated to cost up to $10 billion, will carry 33 billion cubic meters of natural gas annually for 30 years and is extendable.
The final cost, however, is anticipated to be much higher because of an accompanying power transmission pipeline and the fiber optic cable to be laid from Turkmenistan to Pakistan.
Afghanistan will buy about five billion cubic meters of gas once the project is completed. Kabul also will earn up to $500 million in transit fees from the project, which Afghans expect will create about 25,000 jobs in their war-shattered nation.
The Afghan section of the pipeline will run through five provinces in the south and southwest, including Herat, Farah, NImruz, and Helmand, before entering the southern Pakistan city of Quetta.
Security concerns
Taliban insurgents control or contest much of the Afghan territory along the TAPI route, raising security concerns for the pipeline.
In a statement issued Friday, though, the insurgent group dismissed those concerns and pledged to protect the pipeline, reminding skeptics the TAPI was initially negotiated and brought to Afghanistan when the Taliban was ruling the country.
The insurgency, which currently controls or influences about 44 percent of Afghan territory, blamed the 2001 U.S.-led invasion of the country for the delay in TAPI’s implementation.
Groundbreaking for the Afghan section took place at a time when Pakistan’s relations with India have deteriorated and both countries are locked in daily border skirmishes in Kashmir.
TAPI is dubbed by some as a “peace pipeline,” citing the potential the project has to promote regional economic and security cooperation. But analysts remain skeptical about future progress in the wake of Islamabad’s prevailing tensions with Kabul and New Delhi.

Amazon’s assault on the retail industry has brought misery to traditional retailers without a strong web presence.
Less well noticed is the patchwork of European companies that are turning the e-commerce revolution to their advantage, supplying online giants with everything from forklift trucks and storage space to cardboard boxes and automated warehouses.
Mainly bricks-and-mortar retailers such as Debenhams, H&M, and Marks & Spencer have faced a torrid few years as stretched consumers increasingly look online for bargains.
Online retail sales are growing at double-digit percentage rates in every western European country, according to consultancy the Centre for Retail Research.
In Britain, a fifth of transactions are now conducted online, a five-fold increase over the last decade.
The world’s dominant online retailer Amazon, whose shares have soared 73 percent in the last year, is outside the remit of most European investors because it is U.S. listed, so they have had to look for other ways of buying into the trend.
One is investing in companies that have benefited from the rise of e-commerce.
On February 16, warehouse owner Segro’s shares hit a decade-high after it said space-hungry clients, many in online retail and logistics, continued to buy up storage.
“There is a bull market in impatience,” said Gary Paulin, head of global equities at broker Northern Trust. “Consumers want things sooner, faster, now.”
He advises clients to buy shares in Kion, a German forklift truck-maker that is automating warehouses for online retailers, speeding up deliveries in the process.
He also flagged a turnaround at online supermarket Ocado. The company has long been targeted by short-sellers betting its share price will fall, but recently it has signed tie-ups with food retailers Casino and Sobeys, and its shares have more-than-doubled since November.
Martin Todd, a fund manager at Hermes Investment Management, owns shares in Kion as well as DS Smith, a cardboard-box maker which supplies Amazon as well as a number of other online retailers.
DS Smith is developing technology to custom-make boxes for Amazon that will help reduce large gaps in packages that increase freight costs.
“You might think it is a pretty unsexy business … [but] it is getting more high tech in what is traditionally a very low tech industry,” Todd said.
The company recently entered Britain’s blue-chip FTSE 100 index for the first time.
Buying some stocks exposed to online retail does not come cheap. Ocado shares are currently trading at more than 800 times forecast earnings, according to Eikon data.
John Bennett, head of European equities at Janus Henderson Investors, said while traditional retailers were “absolutely dying,” stocks such as Kion were too expensive for him to own.
“It became a very popular name, and I tend to shy away [from widely-owned companies],” he said. “I am far too curmudgeonly on the multiples you pay.”

Saudi Arabia will stage more than 5,000 shows, festivals and concerts in 2018, double the number of last year, as it tries to shake off its conservative image in a drive to keep tourist dollars at home and lure in visitors.
The state wants to capture up to a quarter of the $20 billion currently spent overseas every year by Saudis seeking entertainment, lifting a ban on cinemas and putting on shows by Western artists.
U.S. rapper Nelly performed in Jeddah in December, albeit to a men-only crowd, and Greek musician Yanni played to a mixed-gender audience.
The gradual relaxing of gender segregation risks causing a backlash from religious conservatives, but public objections to a wider program of reforms have been more muted in recent months after several critics were arrested.
At an event to launch the 2018 entertainment calendar, Ahmed al-Khatib, chairman of the state-run General Entertainment Authority (GEA), said infrastructure investments over the next decade would reach 240 billion riyals ($64 billion), including an opera house to be completed around 2022.
That will contribute 18 billion riyals to annual GDP and generate 224,000 new jobs by 2030, the GEA said.
“The bridge is starting to reverse,” Khatib said, referring to the causeway linking Saudi Arabia with more liberal Bahrain where many Saudis flock for weekend getaways.
“And I promise you that we will reverse this migration, and people from Dubai, Kuwait and Bahrain will come to Saudi.”
However, on Thursday night, the Minister of Culture and Information said Khatib’s opera plans were an infringement of the role of the General Authority for Culture, a separate government body, the Saudi Press Agency said.
Economic hopes
The entertainment plans are largely motivated by economics, part of a reform program to diversify the economy away from oil and create jobs for young Saudis.
The Vision 2030 plan aims to increase household spending on cultural and entertainment events inside the kingdom to 6 percent by 2030 from 2.9 percent.
“We are bringing the most exciting and famous events to Saudi Arabia this year,” Khatib told Reuters in an interview, adding that state-sponsored entertainment events would be staged in 56 cities.
“We are creating new local events with local content,” he said. “Almost 80 percent of the calendar [events] are for families.”
Saudi Arabia lifted a 35-year ban on cinemas late last year, with plans for regional and global chains to open more than 300 movie theaters by 2030. The first cinemas are expected to start showing films in March.
Last year, the country announced plans to develop resorts on some 50 islands off the Red Sea coast and an entertainment city south of Riyadh featuring golf courses, car racing tracks and a Six Flags theme park.

The European Central Bank has set a deadline of Friday for Latvia’s third-largest bank to plug a financing hole, the country’s finance minister said, as the Baltic state faced its worst financial difficulties in almost a decade.
Earlier, ABLV said it had asked for a 480 million euro ($591 million) emergency loan from the country’s central bank as part of efforts to reopen for business after being forced to halt all payments in the face of money laundering accusations.
The request for credit comes amid frantic efforts by ABLV’s management to keep the bank afloat after U.S. authorities singled it out for money laundering and moved to block it from doing financial deals in dollars.
ABLV has denied any such wrongdoing. “We want to give an opportunity … for the bank to ensure its short-term liquidity, so that it can continue operating,” the Baltic state’s finance minister, Dana Reizniece-Ozola, told a news website, Delfi.lv.
The ECB has imposed a moratorium stopping savers withdrawing their funds or making payments. It declined to comment about the deadline.
In an interview with Reuters, a senior ABLV executive appealed for the group to be spared closure.
“We believe that the bank has a future, on the basis of a substantially reduced business,” Vadims Reinfelds, deputy chief executive, said.
“What we are looking for here is a medium term or even longer term solution. If that is not possible, then resolution is the alternative,” he said, referring to a possible winding down. “The business can be restructured without resolution,” Reinfelds said, adding the bank was solvent.
He warned the bank was “systemic” — a reference to its significance for the financial system and an indication that its problems could spill over to affect others.
The finance minister, however, played down such concerns.
The crisis at ABLV comes alongside a separate police investigation into whether the head of Latvia’s central bank took a bribe of more than 100,000 euros.
Ilmars Rimsevics has dismissed the allegations and said he is the victim of a smear campaign, while the Ministry of Defense has suggested that disinformation may be to blame.
The ministry did not say who was behind this but drew parallels with campaigns before the U.S. elections in 2016. Russia has denied it was behind those campaigns and says it does not meddle in elections in the West.
The episode has cast a shadow over Latvia, which belongs to the euro zone and whose top officials hold influential posts both at the European Commission and European Central Bank.
Experts have said the events raise questions about the ECB, which is responsible for supervision of ABLV and other banks around the euro zone. The ECB has said it is not its responsibility to police money laundering.
Latvia was one of the hardest hit countries in the global financial crisis, falling into recession as the government sought an international bailout, nationalized Parex Bank and made spending cuts amid a wave of emigration.

Afghanistan will host leaders from Turkmenistan, Pakistan and India on Friday for the ground-breaking ceremony of the Afghan section of a much-delayed multi-billion dollar gas pipeline connecting the four nations.
The $10 billion mega project, known as Turkmenistan-Pakistan-Afghanistan-India, or TAPI, will connect Central Asia with South Asia and is expected to become operational this year.
The 1,814-kilometer pipeline will carry an estimated 33 billion cubic meters of natural gas annually for the next 30 years from the world’s fourth-largest reserves in Turkmenistan.
Officials say India and Pakistan would buy around 14 billion cubic meters each, while the remaining five billion would go to Afghanistan.
Friday’s inaugural ceremony will take place in the western Afghan city of Herat where President Ashraf Ghani, his Turkmen counterpart, Gurbanguly Berdymukhammedov, Pakistani Prime Minister Shahid Khaqan Abbasi and India’s Minister of State for External Affairs MJ Akbar will be in attendance.
Turkmenistan launched construction of its section of the pipeline in December 2015.
Pakistan’s relations with Afghanistan and India have since deteriorated over allegations Islamabad is not doing enough to stop terrorist groups from using its soil for attacks against the neighboring countries.Pakistani officials deny the charges.
But despite the tensions, energy-deficient India is showing renewed interest in TAPI and pushing for its operationalization, according to Indian media reports.
“Today, given the energy requirements in India, there are several gas pipeline proposals before us. We are, however, strongly committed to TAPI pipeline project,” Akbar was quoted as saying.
The project is more than the sum of four nations’ interests and creates a benchmark for regional cooperation, he added during an implementation committee meeting in Turkmenistan.
Economic milestone
The Afghan government and business community also see the pipeline as a milestone in the war-shattered country’s economic development. Kabul is expected to earn up to $500 annually in transit duties and the project will help create as many as 25,000 jobs, local media quoted Afghan analysts.
The pipeline mostly runs through parts of southwestern Afghanistan where the Taliban insurgency controls or influences many districts. But a spokesman for the insurgent group, Zabihullah Mujahid, says it supports the project and will ensure the pipeline’s protection.
Herat Governor Mohammad Asif Rahimi told VOA the Afghan and Turkmen presidents will additionally inaugurate work on the construction of a railway link between the two countries, as well as fiber optic connection along the TAPI route.

It’s pretty extraordinary for people in their 80s and 90s to keep the same sharp memory as someone several decades younger, and now scientists are peeking into the brains of these “superagers” to uncover their secret.
The work is the flip side of the disappointing hunt for new drugs to fight or prevent Alzheimer’s disease.
Instead, “why don’t we figure out what it is we might need to do to maximize our memory?” said neuroscientist Emily Rogalski, who leads the SuperAging study at Chicago’s Northwestern University.
Parts of the brain shrink with age, one of the reasons why most people experience a gradual slowing of at least some types of memory late in life, even if they avoid diseases like Alzheimer’s.
But it turns out that superagers’ brains aren’t shrinking nearly as fast as their peers’. And autopsies of the first superagers to die during the study show they harbor a lot more of a special kind of nerve cell in a deep brain region that’s important for attention, Rogalski told a recent meeting of the American Association for the Advancement of Science.
These elite elders are “more than just an oddity or a rarity,” said neuroscientist Molly Wagster of the National Institute on Aging, which helps fund the research. “There’s the potential for learning an enormous amount and applying it to the rest of us, and even to those who may be on a trajectory for some type of neurodegenerative disease.”
What does it take to be a superager? A youthful brain in the body of someone 80 or older. Rogalski’s team has given a battery of tests to more than 1,000 people who thought they’d qualify, and only about 5 percent pass. The key memory challenge: Listen to 15 unrelated words, and a half-hour later recall at least nine. That’s the norm for 50-year-olds, but the average 80-year-old recalls five. Some superagers remember them all.
“It doesn’t mean you’re any smarter,” stressed superager William “Bill” Gurolnick, who turns 87 next month and joined the study two years ago.
Nor can he credit protective genes: Gurolnick’s father developed Alzheimer’s in his 50s. He thinks his own stellar memory is bolstered by keeping busy. He bikes, and plays tennis and water volleyball. He stays social through regular lunches and meetings with a men’s group he co-founded.
“Absolutely that’s a critical factor about keeping your wits about you,” exclaimed Gurolnick, fresh off his monthly gin game.
Rogalski’s superagers tend to be extroverts and report strong social networks, but otherwise they come from all walks of life, making it hard to find a common trait for brain health. Some went to college, some didn’t. Some have high IQs, some are average. She’s studied people who’ve experienced enormous trauma, including a Holocaust survivor; fitness buffs and smokers; teetotalers and those who tout a nightly martini.
But deep in their brains is where she’s finding compelling hints that somehow, superagers are more resilient against the ravages of time.
Early on, brain scans showed that a superager’s cortex – an outer brain layer critical for memory and other key functions – is much thicker than normal for their age. It looks more like the cortex of healthy 50- and 60-year-olds.
It’s not clear if they were born that way. But Rogalski’s team found another possible explanation: A superager’s cortex doesn’t shrink as fast. Over 18 months, average 80-somethings experienced more than twice the rate of loss.
Another clue: Deeper in the brain, that attention region is larger in superagers, too. And inside, autopsies showed that brain region was packed with unusual large, spindly neurons – a special and little understood type called von Economo neurons thought to play a role in social processing and awareness.
The superagers had four to five times more of those neurons than the typical octogenarian, Rogalski said – more even than the average young adult.
The Northwestern study isn’t the only attempt at unraveling long-lasting memory. At the University of California, Irvine, Dr. Claudia Kawas studies the oldest-old, people 90 and above. Some have Alzheimer’s. Some have maintained excellent memory and some are in between.
About 40 percent of the oldest-old who showed no symptoms of dementia in life nonetheless have full-fledged signs of Alzheimer’s disease in their brains at death, Kawas told the AAAS meeting.
Rogalski also found varying amounts of amyloid and tau, hallmark Alzheimer’s proteins, in the brains of some superagers.
Now scientists are exploring how these people deflect damage. Maybe superagers have different pathways to brain health.
“They are living long and living well,” Rogalski said. “Are there modifiable things we can think about today, in our everyday lives” to do the same?
