I have read, here on lesswrong, that aging may basically stop somewhere around age 100: Your probability of death reaches 50% per year and doesn't go much higher; the reason people don't live much over 100 is just the improbability of the conjuction 50%*50%*50%, etc.
However, this table from the SSA seems to directly contradict that. Now I'm wondering what explains the seeming contradiction.
FWIW, from a histogram I quickly made from the data in http://en.wikipedia.org/wiki/List_of_the_verified_oldest_people it doesn't look like the probability of surviving to age x falls any faster than exponentially.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
