I thought one of the big differences between this and WWE was the size of the guys. Do they have "proper" jobs as well, as it didn't look like they put in the hours at the gym that the WWE guys did, or take performance enhancing substances that may be used elsewhere?
The film The Wrestler is very good, and shows the problem of using steroids, then getting injured, so needing to take painkillers to be able to work etc, and there have been many sad stories of wrestlers over the years.
Some of the famous US stars from years gone by have admitted they used to do steroids, as back then it was "normal", there was pressure to look big, perform well, and "everyone else" was doing it so you "had to" if you wanted to work
