The Epic of Gilgamesh
This is the most fucked up thing I've seen. The VA has this animated film as a training guide for doctors who deal with military personal with post-traumatic stress.
Doctors are made to watch the tale of Gilgamesh. An ancient warrior who seeks out a doctor who talks like a forties comedian. The doctor tells Gilgamesh the cure to PTSD is exercise and showering often. I'm serious.
Doctor: Absolutely. The guidelines have a lot of practical suggestions to keep us focused on improving your long-term health status.
Doctor: Simple things, like exercise, sleep, hygiene and a few less lattes in the morning.
Here is the video.
