How'd he die? How old is Randy Savage? These guys are ODing on something - whatever it is they are ODing on it. It's not steroids - and if it is they are probably ODing from it (water retention, etc.).
Not sure if that is making sense but these people have to be overdoing it at a given time, it's not progressive drug use that is doing them in is my guess. There is no way it works like that - some guys can get away with 30-40 years of use whereas others can't get away with two years. None of the other OD drugs work like that - cocaine, heroin, etc. as near as I can tell. They've got to be taking too much of something at a time.
