i heard an interview from Curt Angle or was it Sting
on radio ,
anyways
dudes said Wrestling is comparable to a circus , they have to wrestle or they dont get paid not many have contracts , most get paid by the event.
He said that due to injuries in the ring, they take lots of pain killers to perform night after night or they dont see a paycheck, due to the pain killer they take it numbs them and slows them down, so they do alot of coke to get amped before a match, and after the match back to the pain killers and hit the road to the next show, along they way they drink heavily most are alcoholics due to never being at home and having wife/family issues at home
Not to mention Vince would fine anyone that looked like weak shit, he wanted all his Wrestlers to be bigger then life, so it was mandatory they were on Steroids
Loads of Painkillers + Steriods + Coke + Booze = Heart attack
