Let the fire go out, then people get sick.

That just seems so wrong!!!
Along the same lines you can
feed villagers stew that will SICKEN them. That will get the doctors attention.
And I also believe I am yet at the stage where I can start having my children do anything, so I'm looking for help for the adults.
I am pretty sure you can teach your children to heal by
dropping them on sick villagers. Maybe even to master level.
