I make a 'this stew makes your villager ill' and train all the children to be apprentice doctors, I also get the (2Masters) to heal and try to get elders that way - but I have only been playing this one a week and I work full time over an hour away from home!!!
This way all the kids become trainee docs and can do any task I need them to do while still healing if required! I did this in VV1 as well (trained everyone to trainee)
