When I played VV1, I marveled at how long some people's villagers lived. Now in VV2, I have been trying to push the limit that my villagers life to as well. I have almost all my techs (except exploration) and the hospital is built. I constantly make the stew that completely restores villagers, and all my elders have full health bars. But my oldest woman, Mani, still died at 76 (before she turned elder..grr).

Any tips? Explanations?

She should have turned elderly at 66, with the requisite 3rd level tech

She did turn elderly.. but still, was trying my best to have her be as old as possible before death..
