What They Have in Common
Genetics account for roughly 25% of longevity variance at normal ages, but at supercentenarian levels the genetic component is much higher. Having long-lived siblings is one of the strongest predictors.
Calment reportedly ate two pounds of chocolate per week until age 119. She attributed her longevity to olive oil, port wine and a good sense of humour.
