What the Average Gets Wrong About Aging

Good Morning.

Ask people to describe aging and the answer is usually some version of the same story.

A little slower each year. A little weaker. A little more forgetful.

It's a picture reinforced by statistics. Average walking speed declines with age. Average cognitive performance changes over time. Average physical function gradually decreases.

The problem is that averages don't describe people. They describe groups.

Researchers at Yale University recently took a different approach. Instead of focusing on the average trajectory of aging, they followed more than 11,000 Americans over the age of 65 for up to twelve years, tracking changes in both walking speed and cognitive function.

The results told a far more complicated story.

Nearly half of the participants improved in physical function, cognitive function, or both during the study. Some declined, as expected. Others remained relatively stable. But many moved in the opposite direction, challenging the idea that aging follows a single, predictable path.

One reason this has gone largely unnoticed is that averages smooth out individual lives.

Imagine one person becomes significantly stronger while another experiences an equally large decline. On average, it appears that nothing unusual happened. But for those two people, the experience of aging was completely different.

The researchers also found that older adults with more positive views of aging were more likely to experience improvement. The study doesn't show that attitude alone caused those changes, but it suggests that the way people think about aging may be connected to the choices they make, the opportunities they pursue, and the outcomes they experience.

The findings don't suggest that everyone grows stronger with age or that decline disappears.

They suggest something equally important.

Growing older isn't one story.

Some people decline. Some remain remarkably stable. And some continue to improve in ways that conventional assumptions rarely acknowledge.

Perhaps that's the real lesson from the Yale study. Aging isn't simply measured by the average. It's lived one person at a time.

Longevity

Every day in The Long Game (below), we look at one small piece of how we age: a question, a habit, a finding from the research. The Longevity Index is the bigger picture: a 4-minute personalized assessment across six science-backed pillars including nutrition, movement, sleep, stress, social connection, and purpose. You'll get a score, see where you're strong, and see where there's room. It's free, private, and built on peer-reviewed research.

The Long Game
One small thing for a longer life

Try This

After your next meal, take a short walk before you settle in.

Even a few minutes of easy walking after eating can help your muscles pull glucose from the bloodstream, reducing the rise in blood sugar that follows a meal. A review of seven studies found that just two to five minutes of light walking lowered blood sugar more than sitting. No workout clothes needed. A lap around the block or even around the house is enough.

Movement is one of the six factors that shape how well we age. The Worthyest Longevity Index measures all six in 4 minutes. Yours, personalized. Get your score →
