Genealogy and DNA site Ancestry once partnered with Google’s stealthy life extension spinoff, a company called Calico, to study the genetics of longevity.
The new study suggests that our genes play less of a role in how long we live than previously believed.
Instead, traits and behaviors that include everything from diet and exercise to how friendly we are appear to play a strong role in longevity.
But surprisingly, we still pass these traits on through generations — mostly by picking partners who look and act like us, the researchers suggest.

The road to achieving a long life is littered with hype. The usual life-extension suspects include pricey pills and supplements; the peculiar involve infusions of young blood and chambers pumped with sub-zero temperatures.

Then there’s science. And one scientific factor that has long been presumed to dictate much of how long we live is our DNA. For decades, it was assumed that the genes we inherit from our parents explain anywhere from 15% to 30% of the variations in longevity that are observed between people.

But a new study that came from a quiet collaboration between genetics company Ancestry and a Google life-extension spinoff called Calico suggests that our genes play less of a role in our lifespan than we thought.

Instead, traits and behaviors that include everything from diet and exercise to how friendly we are appear to play a strong role in longevity. Surprisingly, we still pass these traits on through generations — mostly by picking partners who look and act like us, the researchers report.
