I recently made a big update in my model of how much influence one can have on one’s longevity. I had thought that genetics accounted for the vast majority of variance, but it turns out the real number is something like 20-30%. This necessitates more effort thinking about optimizing lifestyle factors. Does anyone know of a good attempt at a quantified analysis of how lifestyle factors affect lifespan? Most of the resources I find make vague qualitative claims, as such, it’s hard to compare between different classes of risks.
My impression is that unusually high longevity is strongly influenced by genes, but that still might leave open the possibility that lifestyle makes a big difference in the midrange.

genetics heritability longevity
into Google Scholar; first hit says:Does this imply that the other 75% is due to life choices? This doesn’t obvious to me.
No, that is not what heritability means. The other 75% is the myriad of other influences of environment, chaotic chance and life choices.
