Older adults who maintain meaningful relationships and remain socially engaged may benefit from emotional support, mental stimulation, and a greater sense of purpose.

This doesn’t mean that having a large social circle guarantees longevity.

Rather, it highlights how complicated healthy aging really is.

A long life is the result of many interacting factors—not one ingredient.

What Can We Learn From a 117-Year-Old?

Perhaps the most valuable lesson isn’t discovering a secret food.

It’s understanding that exceptional longevity is multifactorial.

If researchers study the DNA of a person who reaches 117, they may identify interesting biological characteristics that could help scientists understand aging.

But that doesn’t mean researchers can simply translate those findings into a supermarket shopping list.

Genetics may explain part of the person’s exceptional lifespan.

Their lifestyle may explain another part.

Their environment, healthcare, habits, relationships, and chance may explain additional pieces.

And there may still be factors scientists don’t fully understand.
