The chicken-egg dilemma is an interesting one.  I'd bet on 50/50. It was just a thought that had hit me.  Seeing opiate addiction in pro wrestling was pretty common back in my day (but less so now, thank goodness) so it was hard to compare addiction rates of shitlords vs. fatties.  But it's startling when I started to mull things over.  Today's generation of workers have a LOT less addiction issues...except the "big men."  It seems like the fat workers are just as strung out as the old days.  And when I thought about it more and more, I don't think I ever met a single lardbucket that wasn't on some kind of painkiller, if not outright addicted to opiates, prescription or otherwise.
