America’s Oldest Woman Turns 116 as Longevity Remains a Scientific Puzzle

Naomi Whitehead has reached the age of 116, a milestone that puts the spotlight on one of science’s enduring questions: why do some people live far longer than others?

Her story goes beyond an exceptional birthday. Research into longevity points to an interplay between genes, lifestyle and environment, rather than a single factor that can explain such a long life.

Genetic traits may help shape a person’s chances of reaching an advanced age, but they do not operate in isolation. Daily habits and the conditions in which people live also form part of the picture.

That complexity makes the lives of exceptionally old people valuable to researchers, while also limiting what can be learned from any one individual. A habit shared by some long-lived people is not necessarily the reason they survived so long.

Whitehead’s birthday offers a striking example of human longevity, but not a proven formula for achieving it. Despite continuing research, there is still no single confirmed recipe for living to such an extraordinary age.
