My guess is that Bob wasn't/isn't very addicted to a certain physique, like a roided physique. He could look more impressive from bodybuilding perspective but he probably doesn't care. Well, evidently he doesn't care. He would probably lean out at record speed if he wanted to, favorable bodybuilding genetics do exist.
Do you think most regular folks immediately identify him as a bodybuilder? My guess is no. People think "ripped" is "huge" and veins mean "steroids." Fucking Brad Pitt in that movie is jacked.
Just now remembered something Lol. Bob said he isn't addicted to anything, I think this was in relation to talking about Tom Prince. Said he was only addicted to sex. I think he removed his prostate as a preventative measure but I don't know if I'd do it even if I had family history - big chance of impotence from what I read.
