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…”

by Alexander Gelfand

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: Ikaria – A Small Greek Island With Oldest Life Expectancy

Ikaria, a tiny island in the Aegean sea, is known as a blue zone, a special place where life expectancy is much higher than the rest of the world. We travel there to explore just what it is that makes the island so special.

New Study: Nearly 50% Of Americans Will Have Obesity By 2030, 25% Severely Obese (NEJM)

From a New England Journal of Medicine online study release:

The findings from our approach suggest with high predictive accuracy that by 2030 nearly 1 in 2 adults will have obesity (48.9%; 95% confidence interval [CI], 47.7 to 50.1), and the prevalence will be higher than 50% in 29 states and not below 35% in any state.

Nearly 1 in 4 adults is projected to have severe obesity by 2030 (24.2%; 95% CI, 22.9 to 25.5), and the prevalence will be higher than 25% in 25 states. We predict that, nationally, severe obesity is likely to become the most common BMI category among women (27.6%; 95% CI, 26.1 to 29.2), non-Hispanic black adults (31.7%; 95% CI, 29.9 to 33.4), and low-income adults (31.7%; 95% CI, 30.2 to 33.2).

Projected National Prevalence of BMI Categories in 2030, According to Demographic Subgroup. New England Journal of Medicine December 2019

Although severe obesity was once a rare condition, our findings suggest that it will soon be the most common BMI category in the patient populations of many health care providers. Given that health professionals are often poorly prepared to treat obesity,27 this impending burden of severe obesity and associated medical complications has implications for medical practice and education.

In addition to the profound health effects, such as increased rates of chronic disease and negative consequences on life expectancy,25,28 the effect of weight stigma29 may have far-reaching implications for socioeconomic disparities as severe obesity becomes the most common BMI category among low-income adults in nearly every state.
