Indeed. As a male in the US if you make it to 75 you'll live about 11 more years on average. Interestingly though that's only a four year improvement over where it was at in 1900. I think it implies most of those people are pushing the edge of average genetic longevity and that medical tech has struggled to do much for non-super longevity people once you're over that general ~75 threshold. That is, my opinion is the overwhelming majority of the the factor/s that get you from 75 to 100 or more, are genetic (and if you don't have super longevity genes, almost nothing will get you to ~100).
