I haven't read the rest of these posts, but I'll share my 2 cents...
I'm 28yrs old, 5'10" and 185lbs with 7% body fat, I wrestled for 15yrs through college, boxed for 6yrs, kickboxed for 8yrs now, and have been training brazilian Jiu Jitsu and fighting amatuer MMA for 3yrs now. I've also been riding bulls since I was 9, professionally for 10yrs now. WITHOUT TRYING TO BRAG, if there's someone out there notably tougher than me, then I'd like to meet him.
Not quite 2 years ago, I had a home invasion, thank God my wife (then fiancee) was not home. I had fallen asleep on the couch, with my Glock on my nightstand in the bed room, and the guys were inside before I knew what hit me, literally. I got the $hit beat out of me by 3 guys, and was left for dead in my own house. All they took was my TV, some guns, and my work laptop.
How well trained I am and how tough I am didn't mean jack. I broke both of my hands fighting back, which is how they ended up catching one of the guys when he went to the hospital for a broken cheekbone, but even still, "you should have seen the other guy" wasn't applicable for me. Some broken ribs, broken nose, broken bones in both hands, 4 mos eating through a straw for a broken jaw, extreme loss of vision in my left eye, and a few new fake teeth (bull riders and boxers earn fake teeth, so I had a few already).
Moral of the story, there's always someone tougher, and 2 is more than one. One on one, you might be the baddest cat on the planet, if so, I'll give Jon Jones, GSP, or JDS a call (pick your weight), but frankly, I'll keep my Glock handy, thanks.
