The Social Security Administration in the United States publishes an Actuarial Life Table that is updated once in a while based on recent experience of life expectancy at various ages, going all the way up to age 119. This table always UNDERestimates a person's probability of living into the future, because the experience of each age group keeps getting better (that is, the death rate keeps decreasing) for each age group over time.

Someone posted a nice infographic where you could put in your age and it would give you some simulated death ages.

I think I saw that posted to HN back in the day. I've recently been looking up new information about longevity, and a link I've not seen posted here before, from the Harvard Gazette,

is interesting on the long-term trend of increasing life expectancy.
