I just noticed in one of my villages, the people are dying in their early to mid-seventies. But some of my headstones have ages in the 80's. Is there some way to treat them that helps them live longer? Or is it that I changed the game from easy to hard recently? They have so much food it'd take them 10 yrs to eat it, they passed 50 Elders long ago, so now they can relax a lot, I keep the pop under 50 (don't like seeing the screen so busybusy). So I don't see what I could change to make them healthier. Any ideas?
