How working out your ageotype could help you live healthier for longer
Your body is ageing down one of four – or more – possible pathways. Figuring out your “ageotype” could help you zero in on the things you can do to stay healthier for longer
THERE is a (probably apocryphal) story about Henry Ford sending agents out to junkyards across the US in search of scrapped Model Ts. The famous industrialist wanted to know which of the car’s vital components failed first, so he could do something about it. The agents reported back that every bit of the car was susceptible to failure, but some were more susceptible than others, except for one – a component of the steering system called the kingpin, which almost never failed. They expected Ford to announce plans to extend the working lives of the weaker components. Instead, he ordered his engineers to make less resilient kingpins. No point wasting good money on a component that always outlived the others.

Medical Technology: AI To Live Longer And Healthier
Renowned researchers like Nir Barzilai have long advocated for a shift in focus towards curing aging itself, but recent advancements could allow us to harness the power of AI to living not just longer, but healthier lives.
In this video, we talk with the scientists behind the groundbreaking discoveries of new anti-aging molecules and visit a lab in Berlin where similar discoveries are made.
Reviews: “A New Way Of Thinking About Aging”
“People 50 and older hold the vast majority of wealth in the country, but we’re producing products and services for people who don’t have nearly as much money to spend…”
April 27, 2023: Thanks to advances in medicine and public health, people are living longer, healthier lives. The world’s population of people 60 and older is growing five times faster than the population as a whole. Global life expectancy has doubled since 1900, and experts say that children born in developed countries now have a good chance of living to 100.
A “silver tsunami” is already sweeping the U.S. labor force: the Bureau of Labor Statistics projects that 36% of people ages 65–69 will remain on the job in 2024 — up significantly from the 22% who were working in 1994.
These longer-lived, longer-working individuals generate an ever-bigger slice of global GDP and control an expanding tranche of global wealth. In her recent book Stage (Not Age), Golden estimates that the “longevity economy” is worth more than $22 trillion — $8.3 trillion in the United States alone.
That may be a conservative figure: AARP (the organization formerly known as the American Association of Retired Persons) estimates that people over 50 already account for half of consumer spending worldwide, or $35 trillion. (This range of figures may have to do with how “older adult” is defined: The term is variously used to refer to people over the ages of 65, 60, or — sorry, Gen Xers — 50.)
Healthy Aging: ‘Outlive – The Science And Art Of Longevity’ By Peter Attia
Trained as an oncological surgeon, Attia became interested in longevity because he saw that the “Four Horsemen” worked against it: diabetes, heart disease, cancer, and Alzheimer’s disease. All play a role in an unhealthy system, and all interrelate.
‘OUTLIVE – THE SCIENCE & ART OF LONGEVITY’ BY PETER ATTIA, MD
A data- and anecdote-rich invitation to live better, and perhaps a little longer, by making scientifically smart choices.
If you have Type 2 diabetes, then your chances of developing heart disease, cancer, and neurological disorders increases, and if your goal is to live well in old age, then it behooves you to change your ways in order to keep your insulin reception levels in the clear. How to do so?
Medicine: AI Verifies ‘Brain Age’ To Detect Alzheimer’s
Researchers at USC have developed a new artificial intelligence model that more accurately captures brain age. This study could result in earlier detection of Alzheimer’s and other cognitive diseases and provide important information about how quickly our brains age.
Aging: 34% Of The Elderly Feel ‘Socially Isolated’
In 2023, one in three adults age 50–80 (34%) reported feeling isolated from others (29% some of the time, 5% often) in the past year. This represents a marked decline compared with the 56% (43% some of the time, 13% often) who felt isolated in 2020, but a greater proportion than the 27% (22% some of the time, 5% often) who reported feeling isolated in 2018.
National Poll On Healthy Aging (March 2023) – More than one in three older adults (37%) reported feeling a lack of companionship (29% some of the time, 8% often) in the past year, compared with 41% (32% some of the time, 9% often) in 2020, and 34% (26% some of the time, 8% often) in 2018.
One in three older adults (33%) reported infrequent contact (once a week or less) with people from outside their home in 2023 (14% once a week, 10% every 2–3 weeks, 9% once a month or less). This rate of infrequent contact was significantly less than the 46% reported in 2020 (19% once a week, 11% every 2–3 weeks, 16% once a month or less), but higher than the 28% reported in 2018 (15% once a week, 7% every 2–3 weeks, 6% once a month or less).
