How old is a villager when they die in virtual villagers?

it depends how much research you have done. if you have researched medicine fully, they can live into their late 70's sometimes 80's. If you do not have it completely researched, say if you just have level 1 in medicine, they can die in their 50's. Unless a villager has gotten sick. Then they can die at any age if they are not healed soon enough.
