For the "Skill learning" mechanics, I always picture our character will be able to teach other character with sitting and chatting.
Also, skill progress will lost a bit after character didn't perform that skill related action for a while (They forget!)
Also, what I know about version 42 is also include trait balancing, any chance you guys will discuss that in the future thursdoid?
I always think anxiety / depression should have a serious affect on our character (Even lead to death!).
