I have been thinking about this and I believe it has something to do with pain and hardship. Is it possible that wisdom can only be acieved through pain and hardship? The damn teeth sure cause a bunch of pain and hardship, but I am not sure how much wisdom they bring.
On another note it is quite possible that afer Wednesday my jaw won't make a clicking sound when I eat. That should be good news for anyone who wasn't a fan of that.
