Ok, I started a new game the other day, and all was going well until one of the villagers ate a berry that the shamans warned them about. Needless to say the little guy is no longer with us. (I like my little people to be adventurous, even at a cost.) Since it was a new game I didn't have many tech points, no new spirituality, so basically for a while I had a corpse on the ground. I don't know what possessed me to do this, but I then put my then child on the corpse, and the message came up that the villager had improved in healing! Sure enough, the healing bar in the Details menu was rising every time I put him on the corpse. Anyway. I just thought that was a little amusing, yet morbid, way of getting skill points.
