My dad actually stuck me in boxing back when I was a kid, 12 or so. I kept with it and did some local club boxing in college etc. I still think sparring a little is a great way to get the heart rate up. Enjoyed it very much.
Muay Thai and some of those disciplines are very impressive and those guys are true athletes. It'd be a really bad day to have to fight some of those guys.
Funny story, I'm a lover not a fighter and even though I messed around in a boxing gym on some level for a lot of years, I don't like street fights/bar fights etc. at all, and have only been in exactly 2.5 of them in my whole life.
The .5 actually was with an MMA type guy when I was 27 or 28, at least that's what him and his 2 idiot friends told me about themselves repeatedly as they followed my buddy and I out of a bar in Bozeman, MT., complete with TapOut shirts etc. It was finally obvious he wasn't going to let me walk away. When I squared up, he bum rushed me. As he came, instead of rolling on the ground with him or some such nonsense, I reached out and jerked out his stupid looking lip ring, taking a noticeable piece of lip out with it.
I learned 2 things:
1.Lips bleed ALOT when you jerk one's lip ring out.
2.Lip rings apparently are hard wired directly into the surrender button.
