Every time before I ring the gong, I make the restoring stew and make sure every villager is completely healthy. Then I make sure I have more restoring stew ready and waiting just in case it takes health.

I had a 14 year old girl ring the gong, and it took away her health, but she didn't die. I was able to immediately restore her with the stew. Her health kept going down for awhile, but I could put her on the stew to keep restoring her.

Others get sick, but I make sure that each and every villager is trained in healing before any other task. I actually start them healing others while still a child. That way, they are all doctors in a sense. This seems to work pretty good. It also gives the real doctors a chance to gain healing points while some of the others increase their healing points so much that I make them official doctors.

This is with my original tribe of 115 villagers. That means I have 115 doctors running around!
