Aging Brains Stay Sharper With Daily Housework And Exercise : Shots – Health News : NPR

Now a study finds even simple housework like cooking or cleaning may make a difference in brain health in our 70s and 80s.

“Exercise is an inexpensive way to improve health and our study shows it may have a protective effect on the brain,” says Dr. Aron S. Buchman with Rush University Medical Center in Chicago, who led the study.

Previous research found just 45 minutes of walking three days a week actually increased brain volume among individuals 65 and older.

Obesity, low BMI linked to increased risk of death, study reveals – CNN

(CNN)Excessively high or low body mass index measurements have been linked to an increased risk of dying from nearly every major cause except transport accidents, new research says.

The study, published Wednesday in The Lancet Diabetes and Endocrinology and conducted by scientists at London School of Hygiene and Tropical Medicine, revealed that BMI that’s either too high or too low is tied to increased morbidity from a range of major diseases.

With legalization comes acceptance. With acceptance comes more use by respectable grownups.

About 9 percent of U.S. adults between ages 50 and 64 used marijuana in the the previous year, according to survey results. About 3 percent of people over 65 used the drug in that time period. This appears to be up from years past. In 2013, the same survey reported that 7 percent of middle-aged Americans used marijuana in the previous year, and only 1.4 percent of people over 65.

Simple eye exam may detect Alzheimer’s disease early – Futurity

A noninvasive eye exam may one day be able to screen for Alzheimer’s disease before symptoms appear.

“This technique has great potential to become a screening tool that helps decide who should undergo more expensive and invasive testing for Alzheimer’s disease prior to the appearance of clinical symptoms,” says first author Bliss E. O’Bryhim, a resident physician in the ophthalmology & visual sciences department at Washington University in St. Louis.

Coffee drinkers are more likely to live longer, according to study of half a million people | National Post

Decaf, instant and regular coffee were all linked to health benefits

The study of roughly half a million adults in the U.K. shows that people who drink coffee – even as much as eight or more cups per day – enjoy longevity benefits.

“We found that people who drank two to three cups per day had about a 12 per cent lower risk of death compared to non-coffee drinkers,” Erikka Loftfield, a research fellow at the National Cancer Institute, told NPR.

Anna Mae Blessing, 92, allegedly killed son in Arizona – CNN

(CNN)A 92-year-old woman allegedly killed her son in Arizona because she did not want to be sent to an assisted living facility, authorities said.

Anna Mae Blessing was charged with first degree murder, aggravated assault and kidnapping after authorities found her 72-year-old son dead Monday at their home in Fountain Hills, Maricopa County Sheriff’s Office said.
Blessing hid two pistols in the pockets of her robe and shot her son several times in his bedroom, the sheriff’s office said in a statement.
Her son’s girlfriend was also in the room and said she heard Blessing telling her son she was tired of the way he treated her, court documents said.
“From my understanding, she had thought about it for a few days because there was a dispute regarding her son wanting to put her in an assisted living home,” Maricopa County Sgt. Bryant Vanejas told CNN affiliate KPHO.
Blessing then pointed the gun at her son’s girlfriend, who struggled with her until she lost her grip of the gun. When Blessing pulled out the second pistol from her robe, her son’s girlfriend also knocked it out of her hand, the statement said.

Japan will legally recognise coming of age at 18 instead of 20 | Daily Mail Online

The new law, which is set to take effect in 2022, will see millions of Japanese youths declared adults by statute two years earlier than their elders.

But unfortunately for the new wave of grown-ups – the change still won’t leave them eligible to drink or buy cigarettes.

Japan’s ruling Liberal Democratic Party said the move is intended to spark a population boom amid fears of an age crisis on the island nation.

Nation’s oldest WWII veteran, Richard Overton, turns 112: ‘He’s a crackerjack’ | Fox News

Richard Overton, the nation’s oldest veteran celebrated his 112th birthday on Friday, May 11.

The veteran celebrated his birthday Friday from his home in East Austin, where he’s lived since returning from WWII. The street on which he lives — Richard Overton Avenue — was named in honor of his 111th birthday last year, according to FOX7.

Overturn, who has met former President Barack Obama and former Texas Governor Rick Perry, among other notable people, requires 24/7 in-home care, the Austin American-Statesman reported.

To help with this expense, his family created a GoFundMe page for Overton that has raised more than $230,000 of its $400,000 goal.

5 habits that could help you live 10 years longer

New research shows just how big a difference a few basic lifestyle changes can make.

Americans could add years to their lives with just a handful of healthy habits, a large, new study suggests.

Right now, the typical 50-year-old American can expect to live another 30 to 33 years, according to government statistics. But based on the new study, those who maintain five lifestyle habits could add roughly a decade to that life expectancy.

The key factors include the usual suspects: not smokingeating healthyexercising regularlymaintaining a normal weight; and drinking only in moderation.

But researchers said the new findings put those lifestyle choices in a different perspective.

“Our findings have significant public health implications, because they demonstrate the great potential of diet and lifestyle changes in improving life expectancy,” said senior researcher Dr. Frank Hu. He is chair of nutrition at the Harvard School of Public Health.

Dr. Suzanne Steinbaum, a spokesperson for the American Heart Association, agreed.

A ‘catastrophist’ says longevity poses huge risks we aren’t dealing with.

By Michael Grunwald

Human beings are living longer than ever, which can be a wonderful thing. As the T-shirts say, life is good. But human longevity has big consequences for society, which is one reason President Obama is hosting today’s White House Conference on Aging. It’s great that we can get new hips when our old ones wear out, but someone has to pay for them. It’s great that Baby Boomers will enjoy longer retirements, but will their retirement savings last as long as they will?

Most of us think of longevity as a gift, a blessing, a sign of social progress. Gordon Woo thinks of it as a catastrophe.

Dr. Woo, a Cambridge-trained mathematician and MIT-trained theoretical physicist who now works for the London-based consultancy RMS, spends his days thinking about catastrophic risks. Woo is one of the world’s best-respected “catastrophists,” and RMS—short for Risk Management Solutions—helps insurers and reinsurers calculate the likelihood of disastrous earthquakes, hurricanes, droughts, terrorist attacks, financial crises, and other hazards. Lately, Woo has been thinking a lot about the risks posed by climate change, which could have a huge impact on the catastrophes of the future, altering sea levels, weather patterns, migration patterns, and much more. But Woo’s other major preoccupation these days is the risks posed by people living longer.

Unlike some futurists, Woo does not believe the aging of the population is going to plateau any time soon—not in an era when you’ll be able to replace more of your spare parts and take the drugs that work best for your personal genome. And that could have huge implications in the coming decades, as civilizations struggle to meet the medical and financial needs of their elders.

In the United States, for example, Social Security is now in pretty solid shape, and Medicare’s troubled finances have improved significantly in the last few years, as health care costs have stopped soaring. But the picture could look very different over the next quarter-century, as the portion of Americans over the age of 65 rises from 12 percent to 20 percent. In 1960, there were five American workers for every retiree, but now there are just under three, so Social Security no longer generates surpluses. By 2040, there will be about two workers per retiree, a demographic cliff that could drain the system in a hurry—or force some dramatic changes. And the days when most Americans spent their entire career with the same company and then enjoyed a private pension during retirement are long gone.

New Jersey governor Chris Christie and other Republican candidates for president have called for reining in government entitlements; Jeb Bush has suggested the retirement age may have to be raised to 70. Meanwhile, Elizabeth Warren and other Democrats have talked about making Social Security benefits more generous, to ensure they can provide a high quality of life throughout an extended retirement; in her economic policy speech this morning, Hillary Clinton talked about “defending and enhancing Social Security.”

Woo talked to POLITICO’s Michael Grunwald about what he’s learned about old age—not only its consequences, but what kinds of people are most likely to achieve it, what kinds of medical advances are and aren’t likely to prolong it, and what it will mean for our public and private finances when living into our 90s is the norm rather than the exception.

MG: You have the coolest title ever: “catastrophist.” And you’ve written that the coming longevity catastrophe has a lot in common with the coming climate change catastrophe.

GW: Longevity has two important facts in common with climate change. They are both going to develop gradually over time. And because the attention span of human beings tends to be fairly limited, they are both issues that generally get put on the back burner.

MG: Can you explain why longevity is bad?

GW: At RMS, we’re focusing on the pension retirement sector, and it’s really underfunded in terms of its provision for increasing lifespan in the decades ahead. One reason is that when it comes to making provisions for longevity instead of ecological or geological catastrophes, regulators tend to be fairly light of touch. There’s good reason for this. If a corporation seems to have a black hole in its pension fund, it may not be a good policy to force the corporation to pump more money into the fund while it’s going through hard times, because that very act could draw the corporation into insolvency. That’s why regulators, even if they spot the problem with the pension fund, are often reluctant to force measures to remedy the situation. Often the thinking is, times will get better, corporations will get out of trouble, hopefully everything will be rosy in the future. But that will not be the case.

MG: How much longer are people living? Is this trend going to accelerate going forward?

GW: There is one view within the actuarial community that it might be leveling out—medical discovery is plateauing, it’s getting harder to discover new drugs, there are diminishing returns, that kind of thing. But that perspective doesn’t allow for the expansion of research into whole new territories such as regenerative medicine and anti-aging.

MG: But that’s not going to make people nervous. That’s going to make them excited, right?

GW: They don’t really see what the implications are.

MG: When you’re talking about regenerative medicine, you mean people picking up spare parts as they get older. My mom just got an excellent new hip.

GW: The basic paradigm is automobiles. You can have an automobile which was built 50, 60, 70 years ago, and if you keep repairing or replacing broken or used parts, that automobile can keep going for a very long time. Right now, if you have some disease or failed organ or system, you might have to resort to some kind of a transplant, say a liver transplant or heart transplant. But in the future there should be the possibility of replacing these organs or actually re-growing these organs. Ray Kurzweil, Google’s chief engineer, is advocating a whole new world of 3-D printing, where you can print out an organ in the same way you can print out a sheet of paper. That’s a future where you can maintain an individual for a very long time. Of course, the brain is something else but the rest of the body in principle could be replaced. Just as if you have an emotional attachment to your car, even if the gearbox breaks or you need new tires or a new transmission, you can pretty much can keep that car on the road in perpetuity.

MG: In the last century, how much has longevity increased? What do your models say going forward?

GW: A century ago, the modal age of death, the most common age of dying, was in the 70s. Now it’s reached the mid-80s. People who are dying before 86 or so are essentially dying prematurely.

MG: When will it be 90?

GW: Quite likely in the next few decades. I think people take it for granted now that retirees should be living into their 80s but not necessarily their 90s. That’s the normal expectation. But that will change, and that’s precisely the source of the longevity catastrophe—because retirees who are retiring in their sixties may not have the finances to keep going into their nineties.

MG: In the United States, at least so far, Social Security has held up and you don’t hear stories about elderly people subsisting on dog food or whatever the horror stories were of previous generations.

GW: Well, it’s all about standard of living. People want to enjoy their days in retirement. Public pensions don’t always provide enough for retirees to enjoy a high-quality life. If I could make a point, recently in America there’s been a change of legislation to encourage the market for deferred annuities, essentially longevity insurance. This kind of product would help an awful lot to remedy the problems we’re talking about. An individual can take out this insurance and the insurer pays up if he reaches an advanced age, say 85 or 90. If he doesn’t make it to that age then the insurance is not needed.

MG: It’s like anti-life insurance.

GW: It’s really catastrophe insurance, essentially. If you count living to 90 as being some kind of catastrophe for your finances, then you need this kind of catastrophe insurance.

MG: As people live longer, do they need less health care? Or when you have more old people is that just going to put more of a strain on our Medicare system?

GW: The aim of medical research is to increase not just lifespan but health span, the years of healthy living. The aim is essentially to compress the ages of illness into as few years as possible. If the modal age of death increases from 85 to 90 that wouldn’t be so great if people were just in bed for five more years. The way it would be advantageous is if people could have five more years of healthy living and the actual time period spent in poor health was kept to whatever it is today, possibly shrunk.

MG: You’ve written about how as important as it is to grow new arms and hearts and livers, that actually being able to talk to somebody might be just as important.

GW: That’s entirely right. If you take two individuals who are in good physical shape when they retire, the person who has greater resilience in terms of cognitive, psychological and social functioning is almost certainly going to be living longer. The classic example of someone who is very highly resilient is Jeanne Calment, who to this day holds the world record for being the longest-lived individual. She was French. She died at the age of 122. Most people once they get past 100 don’t function that well cognitively, but Jeanne Calment at 120 was cracking jokes that would have been great for someone 100 years younger. These resilience factors of cognitive functioning, stress-free life, having a sense of positivity about the future, they’re so important, and then also having a good social network, friends and family and so on. Loneliness is well known to be a killer. It’s really unlikely that someone who’s alone is going to live to be 100.

MG: Could you talk a little about some of the public policy implications of all these things? It seems like we should be thinking about pensions, how to get people to sign living wills, how to get old people into social networks.

GW: I do think the U.S. has been farsighted by encouraging this market in longevity insurance. Not everyone will live to 90 or 100, but people should be able to make provision for this contingency. Otherwise, the burden of helping to look after the very elderly falls on the state. And it’s been said that Social Security is essentially like a Ponzi scheme. The government doesn’t have any money to finance future liabilities; they just rely on money that’s coming in through the door at that time. That’s what happens in a Ponzi scheme. You’re just hoping you have enough new people coming in, so you can use the money you rake in to pay your liabilities. Of course, the problem is that with changing demographics, with the population aging and fewer children being born, you have a situation where soon the money coming in for Social Security may not cover the payments going out. So that’s a headache for future governments, just like climate change. But that might be 20 years out, and politicians are only elected for four or five years, so it’s not really front of mind.

MG: What about private pensions? It used to be you could finish high school, go work for General Motors for 40 years, and then you got your pension. Most jobs don’t have pensions now.

GW: That’s right. And the General Motors pension fund was in huge trouble a few years ago. There’s a whole new generation of people who are no longer getting silver-plated pensions, so the pensions are all based on contributions…. And there’s a whole new era coming where pensioners are not going to be as well off as they are now. If you travel to resort areas, you’ll see a lot of tourists who are benefitting from the generous pensions which they were given in the past few decades, pretty much the lucky pensioners to retire when pensions were fairly generous. They’re pretty much the winners of the pension race.

MG: They have a lot of political power, and they tend to be aggressive about protecting their interests. Generally, their interest is not so much the future.

GW: That’s a very interesting point, because I think in a few decades the gray vote is going to become more important than ever. There will be fewer younger voters, and it seems like the policies which focus on retirees will become more important. And older people are more likely to vote than younger people, so you have a situation where retirees will have a lot of fiscal power.

MG: Huh. You hear a lot that Republican voters—who tend to be older, whiter, more rural, and so forth—there’s this sense that they’re dying off and being replaced by a multi-racial, more cosmopolitan, younger generation. But they’re not dying as quickly as they used to, I guess.

GW: We just had a general election in Britain. Younger people tend to be the most outspoken, but it’s like the silent great majority of older voters kind of put the prime minister back in power…Everyone likes to talk about current problems, short-term problems. But in 40 years, longevity is going to create some real stresses. Even in the Western world, people will struggle to get by on what they’ve saved.

MG: Presumably a lot of this depends on behavior. Like in the U.S., are we going to get our obesity problem under control, are we going to eat better, are we going to get more exercise.

GW: Actually, no, obesity is really a problem for people in younger to middle age. People who weigh 300 pounds when they’re teenagers, they’re not going to make it to retirement. The problem with longevity is a problem of how long a retiree can live. If your constitution is such that you reach the age of 60 even though you’re overweight, then that’s not really a problem for you. So obesity may change the life expectancy for the whole U.S. population, but that’s not the longevity problem we’re talking about.

MG: Most people don’t think of it as a problem. But most people aren’t catastrophists. What happens if somebody in a lab cures cancer tomorrow?

GW: Well, cancer doesn’t make that much difference, either; if an aging person doesn’t die of cancer, they’ll die of heart disease. The real issue is that the aging process can be arrested. The biggest cause of death is not cancer or heart disease. The biggest cause of death is aging. If you can slow down the process of aging, you’re slowing down all causes of death. This is new territory for mankind. There’s an interesting book called “Positively Ninety.” It’s interviews with nonagenarians who are all very lively. My favorite is the cover lady, who actually plays competitive Scrabble at the age of 90. She’s very sharp. Very positive attitude towards life. Very good network of friends and family. If you read these interviews with positive nonagenarians, you’ll get a glimpse into the future, because a high proportion of people will be just like that. The 90s will be like the 80s today. And it will become commonplace to reach 100. In fact, for a baby born today, the expectation is already that they will live to 100.
