Actually, human behavior genetics studies suggest that all-cause mortality (and, thus, longevity) has about the lowest calculated "heritability" (which concretely means resemblance among closely related persons) of any measurable human behavioral characteristic. Increases in life expectancy are happening to everybody, and most causes of death have a big stochastic or environmental component in their actual manifestation in individuals.
