The oldest one I ever had reached 80 years before dying:

However, I think that it's possible that someone saw a even older character during a game, even if for those times reaching the seventies was like reaching the nineties today (although rare guys like Massinissa died at 88/90 if I remember well).

So, post here the most venerable kids (...) of any game of yours, obviously not from Alexander. :P
