In my longest-running tribe I've had four villagers live to reach Ancient Elder: one got to 90, two to 92, and one to 95. That's out of 104 who have died so far according to the Roll of the Dead. In my second tribe the oldest villager died at 88 (out of about 30 on the ROD) and my newest tribe has an oldest villager of 78 (only half a dozen have died there so far). All the tribes followed Nature.
