I haven't lost anyone yet and my oldest gentleman is now 72. I'll be sad to see him go as he's my one and only scholar (and he's the very first peep I choose for my tribe) but I could probably use his help as a ghost in locating the final windpipe and two fish scales needed to complete my collections. As of right now, I am at my maximum population of 35 and I only just now started on my third living hut.
