There seems to be a lot of active wrestlers, however, who die while still in their 20s, 30s, or 40s. The British Bulldog, Curt Henning, Big Dick Dudley, Brian Pillman, and Louie Spicolli come to mind as examples from the past few years. There have been many others during this same period. Steroids and/or other drugs seem to be the culprit in many cases (although the cause of death more often than not is listed as a "heart attack"). If you had active NFL, NHL, or Major League Baseball players dying in similar numbers, there would be a Congressional investigation.
I've watched wrestling for many years, and I've noticed that a lot of wrestlers such as Scott Steiner, Chris Benoit, Eddie Guerreo (spelling?) and even Vinnie Mac himself are a lot bigger physically than they were a few years ago. Did they build themselves up "naturally"? Certainly not in the case of Scott Steiner! I suspect that the epidemic of "heart attacks" that have claimed so many wrestlers in recent years is going to continue for the forseeable future.
