Pro wrestling is one of the strangest professions people can get in too
You work on the road nearly the entire year taking all sorts of crazy bumps
Since it is predetermined it isnt governed by any sanctioning body and the wrestlers can accumulate tremendous injuries
Add to that lanyard of the guys are blown up much bigger than they actually should be to have the right wrestling aesthetic. It isnt just the more muscular guys like Benoit carrying a lot of extra muscle, but even the more super heavyweight fat guys. They tend to want to look as big as possible. You have guy like Big Show who has managed to stay healthier long than most the big guys by losing over a 100 pounds. He mentioned he was legitimately around 500 pounds since his thing was being the world's largest athlete.
