I have my two original villagers, one just made Elder today and the other's skill is teaching, researching and she's a very good swimmer (in the pond). They're both 74 at the moment, though the Elder is slightly oder- I'm only guessing because I don't know - but he turns 1 yr older first.
I've been doing the "stew" and allowing him to do what he wants. I'm trying to keep him away from the manual labor - but he's stubbron!! He wants to work, and work he does! I just checked him and he was [ uncovering the ruins ] {highlight between the braquets, there is a spoiler there tho} She stays at the research table, which she's happy with. I try to make sure to drop him/her at the food bin often, he seems weaker than her - prone to "not feeling well", and I think its from the Master Builder in him. We'll see how long I can keep them going - but I sure hear the clock ticking and ooooooooh I'll be sad to see them go!!!!!!
