Digital Life: ‘Is Immortality Possible?’ – Capturing Our Memories For Future Generations (WSJ Video)

Voicebots, Humanoids and Other Tools Capture Memories for Future Generations What happens after we die—digitally, that is? In this documentary, WSJ’s Joanna Stern explores how technology can tell our stories for generations to come. Old photos, letters and tapes. Tech has long allowed us to preserve memories of people long after they have died. But with new tools there are now interactive solutions, including memorialized online accounts, voice bots and even humanoid robots. WSJ’s Joanna Stern journeys across the world to test some of those for a young woman who is living on borrowed time.

Top New Books On Aging: “Exercised” By Daniel E. Lieberman – “Extending Longevity” (Harvard)

HARVARD MAGAZINE (SEPT – OCT 2020): From the book EXERCISED: Why Something We Never Evolved to Do Is Healthy and Rewarding by Daniel E. Lieberman, to be published on September 8, 2020 by Pantheon Books:

‘….many of the mechanisms that slow aging and extend life are turned on by physical activity, especially as we get older. Human health and longevity are thus extended both by and for physical activity.’

What Happens When We Exercise?
The graph breaks total energy expenditure (TEE) into two parts: active energy expenditure, and resting metabolism. Resting metabolism remains elevated for hours even after exercise ceases, burning additional calories in a phase known as excess post-exercise oxygen consumption (EPOC).

Exercise is like scrubbing the kitchen floor so well after a spill that the whole floor ends up being cleaner. The modest stresses caused by exercise trigger a reparative response yielding a general benefit.

In order to elucidate the links between exercise and aging, I propose a corollary to the Grandmother Hypothesis, which I call the Active Grandparent Hypothesis. According to this idea, human longevity was not only selected for but was also made possible by having to work hard during old age to help as many children, grandchildren, and other younger relatives as possible survive and thrive. That is, while there may have been selection for genes (as yet unidentified) that help humans live past the age of 50, there was also selection for genes that repair and maintain our bodies when we are physically active.

Daniel E. Lieberman is a paleoanthropologist at Harvard University, where he is the Edwin M Lerner II Professor of Biological Sciences, and Professor in the Department of Human Evolutionary Biology. He is best known for his research on the evolution of the human head and the evolution of the human body.

Infographics: “Experience With Ageism” For Adults Age 50 – 80 (July 2020)

National Poll On Healthy Aging - University of Michigan

What is everyday ageism and how common is it?

This poll examined older adults’ experiences with nine forms of everyday ageism. These forms were categorized into three groups: (1) exposure to ageist messages, (2) ageism in interpersonal interactions, and (3) internalized ageism (personally held beliefs
about aging and older people).

Studies: Elderly In 3rd Highest Level Of Exercise Reduce Brain Shrinkage, Aging By 4 Years (AAN)

From a March 5, 2020 American Academy of Neurology release:

American Academy of Neurology (AAN) Logo“These results are exciting, as they suggest that people may potentially prevent brain shrinking and the effects of aging on the brain simply by becoming more active,” said study author Yian Gu, Ph.D., of Columbia University in New York and a member of the American Academy of Neurology.

“Recent studies have shown that as people age, physical activity may reduce the risk of cognitive decline and dementia. Our study used brain scans to measure the brain volumes of a diverse group of people and found that those who engaged in the top third highest level of physical activity had a brain volume the equivalent of four years younger in brain aging than people who were at the bottom third activity level.”

Older people who regularly walk, garden, swim or dance may have bigger brains than their inactive peers, according to a preliminary study to be presented at the American Academy of Neurology’s 72nd Annual Meeting in Toronto, Canada, April 25 to May 1, 2020. The effect of exercise was equal to four fewer years of brain aging. The study used magnetic resonance imaging (MRI) scans to measure the brains of people with a range of activity levels, including those who were inactive to those who were very active. The scans showed less active people had smaller brain volume.

Diet Studies: “Eat Less, Live Longer” – Calorie Restriction Delays Age-Related Diseases (Salk)

Salk Institute logoEat less, live longer- If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases and live longer—eat less food. That’s the conclusion of a new study by scientists from the US and China that provides the most detailed report to date of the cellular effects of a calorie-restricted diet in rats.

(Salk News, February 27, 2020)

While the benefits of caloric restriction have long been known, the new results show how this restriction can protect against aging in cellular pathways, as detailed in Cell on February 27, 2020.

Aging is the highest risk factor for many human diseases, including cancer, dementia, diabetes and metabolic syndrome. Caloric restriction has been shown in animal models to be one of the most effective interventions against these age-related diseases. And although researchers know that individual cells undergo many changes as an organism ages, they have not known how caloric restriction might influence these changes.

In the new paper, Belmonte and his collaborators—including three alumni of his Salk lab who are now professors running their own research programs in China—compared rats who ate 30 percent fewer calories with rats on normal diets. The animals’ diets were controlled from age 18 months through 27 months. (In humans, this would be roughly equivalent to someone following a calorie-restricted diet from age 50 through 70.)

Health Talk: “Macular Degeneration” – Diagnosis & Treatment (Mayo Clinic)

On the Mayo Clinic Radio podcast, Dr. Sophie Bakri, a Mayo Clinic ophthalmologist and retina specialist, discusses macular degeneration, a common eye disorder with age. This interview originally aired Feb. 29, 2020.

Dry macular degeneration is a common eye disorder among people over 50. It causes blurred or reduced central vision, due to thinning of the macula (MAK-u-luh). The macula is the part of the retina responsible for clear vision in your direct line of sight.

Dry macular degeneration may first develop in one eye and then affect both. Over time your vision may worsen and affect your ability to do things such as read, drive and recognize faces. But this doesn’t mean you’ll lose all of your sight.

Early detection and self-care measures may delay vision loss due to dry macular degeneration.

Interview: 71-Year Old Model And Dietitian Maye Musk On Getting “More Fabulous” As She Ages

Excerpts from a WSJ. Magazine interview (Feb 24, 2020):

A Woman Makes A Plan Maye Musk bookWell, when you get older, you are more fabulous, actually. You go through a lot of hard times in your life… and then, at this stage you get out of those bad situations quicker and they are less painful. You figure them out, and you move on. And I’m having the best time ever. I’m 71 now, it’s the best time ever, and I think at 81 it will be great. My mom [had] her best times when she was in her 90s. So I look forward to that.

A model since age 15, Maye Musk was in her 60s when her life took a turn for the fabulous. In her seventh decade, the former dietitian appeared in a Beyoncé music video, signed a contract with top modeling agency IMG and became a CoverGirl spokesperson, setting a record as their oldest yet. At the end of last year, Musk, now 71, added memoirist to her resume. Her book, A Woman Makes a Plan: Advice for a Lifetime of Adventure, Beauty and Success, chronicles her career and experience raising her children—SpaceX and Tesla founder Elon, restaurateur and philanthropist Kimbal and filmmaker Tosca—as a single mother who fled a turbulent marriage.

Born in Canada, raised in South Africa and now residing in L.A., Musk spoke to WSJ. about what she eats for breakfast, how she stays on top of emails and why she doesn’t miss hustling all the time.
