You will also probably outlive three nines of humans historically. A woman at my church passed away recently, tragically young at 68. (That is about a decade below the life expectancy of Japanese women of her generation.)
Also, while I generally scoff at scifi, it is entirely possible that we will make big strides against aging this century. I expect my chilren will grow up with their grandparents. I expect their grandkids will not even understand the import of that sentence.
I still have a great-grandmother who is almost 100. It was a very surreal experience when her daughter died, at about 68 or so, and she hosted the viewing.
Can you imagine burying your own elderly daughter?
Reminds me of the abc documentary "Live to be 150... can you do it?" where the profile several centenarians. They look in surprisingly good shape considering they are over 100 years old. See http://abcnews.go.com/Health/Longevity/Story?id=4559263&...
I'm curious where you get your statistics on the detailed distribution of historical human lifespans. They have never been, you know, Gaussian. I think it's always been the case that several humans per thousand survive into their 80s.
