Also, maybe there should be amnesia, gained by having a blunt object(club, battle club) hit your head, and it drops a random skill level by 1(only if it is under 5, because the higher levels are a pain to get, other than swimming and foraging).

Plus that, maybe there could be broken bones, which reduce walkspeed and attack. The skill lose would be temporary.
