You're exactly right -- but why let the truth get in the way of a good stereotype? If a pro wrestler dies, it must have been steroids.
The same sentiments were posted when Reggie White died.
I think half the problem is that a lot of these deaths have to do with weight. A lot are big guys, who eat a lot. When they performed they worked out. When they quit, they slowed down the workouts but kept up the eating. Also pain meds are in there some where (years of them, and not just bening ones like tylenol 3's). Steroids I am sure are a major factor but it for sure isn't the only one.
