As far as I can tell, Trigeminal Neuralgia contributes to all cases of violence or self destruction.

This is Trent Reznor.   He seems to be a pretty obsessively unhappy guy.
Anyhow, in that photo he has the most inflamed maxillary nerve I've ever seen.   It is flaring out on both sides of his nose like a neon sign.  It tends to make your eyebrows pinch like that, too.
His upper lip also shows signs of swelling, like his jaw or teeth are infected.

This is me.     When I was 8.

He seems to be looking better lately.  I hope he's not so angry anymore.  Even though he was very, very good at it.

This guy was very bad at it.
Something to think about. 
Not to mention this.
