Supercentenarians’ DNA Reveals Clues to Human Longevity

By studying the genomes of people over the age of 105, an international team of researchers has identified several genetic factors that appear linked to human longevity — and they center on the body’s ability to repair its own DNA.

The challenge: The world’s average life expectancy is 72 years today, but many people live decades longer.

Research suggests that genetics play a role in human longevity, but we don’t know precisely what it is that allows some people to live so much longer than others.
