Probably a bit of both, but I do think the trauma has something to do with it, probably also some psychological/mood issues associated with steroid use, abuse of pain killers and other drugs and alcohol. The fact that many of these guys don't have many other prospects beyond wrestling may also contribute to some of these problems. When a guy's career is over, he has no other skills, and he's just sitting at home in constant pain, many without families since they gave family life up for a life of wrestling on the road, and I can see how some guys may just kind of give up. It may not result in suicide, but it seems like there are way too many deaths to be random chance. If you pick a random wrestler from your childhood, it's like a 50/50 chance he's dead now.
Having said that, none of this may apply to Warrior, but I wonder if those years of abuse didn't take their toll.
