Age is about how a player feels but in optimal conditions, from what I have read it would be approx 84 turns per year, or 42 days. This changes with how easy or hard of a life the player leads. If a bureaucrat has an easy life he could live 5 years real time, BEFORE he even gets a 0.001% per turn chance of death. That is a small turn over, except for already old players.
That also means, that per game year that person has a 0.084 percent chance of death in the first year. In fact he has a 99.5% chance of living till hes 65.
The turn over would be far, far to low to even bother with. You would have to be really REALLY unlucky to die. Not even worth coding unless its a significant chance, like 0.5 or 1 percent per turn for someone over 60.
In my opinion, if you play from a young noble then its anywhere between 4 and 5 years real time before you get to this point. A 2% chance of dying each day is not a far cry. This is 1013 for petes sake, it really should be 40 because life expectancy for nobles was like 35-45, less for peasants. 50 was considered ancient, and we have a ruler in Perdan who is currently 90 in game. People barely live to 90 now, let alone in 1013.
