A person’s lifespan may be up to 55% heritable, according to new research.

A person's genes play a far greater role in likely lifespan than previously thought, according to a major new study published Thursday in the journal Science.

Using data from human twin studies, an international team of researchers arrived at the conclusion that the genetic contribution to how long we're likely to live is as high as 55%.

This new finding is strikingly higher than previous estimates, which have calculated the role of genetics in lifespan could range from 6% to 33%. It’s likely to intrigue — and perhaps disappoint — the fast-growing community of longevity influencers and self-described biohackers touting longer lives through supplements and customized drug regimens.
