Same here, Kuya. I check them all regularly and feed any that are not in perfect health the special "Completely Restored" stew... but that doesn't help, they still all die in their late 70s or early 80s. A few have made it to around 86 or so, but a very few.

It was so frustrating that, after I'd maxed my Elders and filled the graveyard... (after completing all the puzzles and ringing the gong a few times)... I finally deleted that village and started over with a new one.
