I don't know about that. Out of about 350 relatives, I believe I have two relatives that died before their 80s, if I exclude the ancestor relative that died of an appendicits at 7 about 75 years ago.

Amy, that's phenomenal! But nevertheless, that's only recent history. If you go back a few hundred years, you'll find your direct ancestors were not all living that long.

Women typically have about 10 or 15 children in the wild. So, simple arithmetic says that 80% of those children have to die without reproducing, or the world would have been covered in humans 10 kilometres deep.

My grandmother's siblings said that anyone who died younger than 90 had something wrong with them. I think they all went on at least until their latish 80s.

Among my 17 cousins, we are all still going and the youngest are now into their 40s and the oldest in their mid 70s and they seem all in fairly good condition [though two had prostate cancer]. So that's a good start, though far from 90.
