Biker gangs and bouncers

Werewolf seeking employment. Ok what's with all were's being strong dudes with high risk jobs. There are a few exceptions. I know that Hamilton has a lot of were's that are teachers and such. But mostly you get Bikers and Bouncers. All of which are heavily tattooed. I understand why they are all ripped. I mean you run around on all fours for a bit and you get muscles us fiddle humans can only hope to have. But why does muscular have to mean idiot. At least some are in recon and military work. A few more brain cells for that.
