Well, you have to factor the guy’ s class into it, not just his age.
The problem with the “avg age at time of death” is that it picks up thinks like infant mortality (1.7% in 2002 and 2.9% in 1979). You also have to look at the contribution of wealth and class.
Even there, the better metric for a person might be “expected years of life remaining.” Since someone who is 65 didn’t die in infancy and wasn’t killed as a teen, all of those factors (which drag life expectancy down) can be ignored. If you’re still talking populations and cohorts, you’re still factoring in things like poverty and access to healthcare, but it might give a better understanding of the statistical probability of a person to die of natural causes in a hotel at that age.
