It seems almost impossible. People over 90 who don’t suffer from heart disease, diabetes, or dementia - and who still cook their meals, go for walks, and live independently.
Yet these individuals exist. And they’re not randomly scattered across the world. They tend to cluster in specific regions like Okinawa in Japan and Sardinia in Italy, where the rules of aging appear to bend.
These so-called "blue zones" have caught the attention of scientists.
The residents don’t just live longer by luck. They carry clues - hidden in their bodies and lifestyles - that may reveal how to age with health, not just years.

It’s in their DNA – but that’s not the whole story
Part of the explanation lies in their genes, a new study finds. Many of these long-lived individuals share specific genetic traits.
One is the rare APOE ε2 variant, which seems to protect against heart disease and Alzheimer’s.
Their DNA also shows fewer age-related changes - especially in regions that help maintain genome stability.
But it’s more than just good genes. Their metabolism tends to function differently.

They often have low LDL cholesterol, balanced blood sugar levels, and a heightened ability to fight cellular stress. Essentially, their bodies resist aging from the inside out.
Still, scientists caution that genetics only tell part of the story. The rest lies in daily habits repeated over decades.
Daily life that defies aging
These long-living individuals aren’t counting calories or hitting the gym. Their lifestyle is simple but consistent.
They eat mostly plants - vegetables, nuts, and whole grains dominate their plates.

They move daily, not through structured exercise but by simply staying active in their environment. Most avoid smoking, drink alcohol in moderation, and get enough sleep.
One of the most powerful factors is the low stress and strong social bonds.
Many centenarians stay socially engaged and find meaning in small routines. This emotional resilience may be just as crucial as physical health.
Ultimately, their longevity isn’t about hacks or supplements. It’s about a slow accumulation of small, healthy choices that add up over a lifetime.
