In my security career, I have worked with professionals mostly, so that helps. I grew up in the military moving all the time so I was always the new guy AND a minority. I learned at an early age how niggers fight as a group and how they try to pretend they're your friend to jump you. So, I've been in hundreds of fights.
I used to workout lifting weights, and I try to walk a lot for cardio. Most guys need martial arts training, but I'm a good grappler already. I'm too old for this shit, wrestling guys to the concrete and busting my knees and holding them down to handcuff them and restrain them until the cops arrive. Or doing CPR on some guy for twenty minutes while I'm wearing 50lbs of gear and sweating like a pig.
Tbh I have to trust in my coworkers and training as a team how to fight and restrain.
Oh I did executive transport at music festivals for several years. Here's me hanging out all day backstage with the talent at music festivals, doing blow off stripper's titties while you guys are keeping the rails from breaking.
