"It's hard to say whether the wrestling lifestyle caused Hall to go down this awful road"
....really? Given the amount of wrestlers who are on the road 300 days a year living on popping pills, amphetamines, and booze, and the amount of wrestlers who are broke and are dying at early ages.....what Scott Hall is going through shouldn't be a surprise to anyone. Same goes for Hogan and Flair.....they are both broke now, and have contemplated suicide attempts from what I've read/heard on TV.
You watch and see what goes on behind the curtains of the WWE's and TNA's and it's not pretty. Sting is still in the biz....I would make the assumption that he's in it because he's broke too. Same with Undertaker.
