Back on topic - after say, a normal, moderately successful 8 year career, you are definitely going to be pretty damaged from fighting. I've got joint pain and aches and pains from training a few years at nowhere near the intensity a real pro would. Most fighters/athletes probably don't end up regretting it, though a lot do. It raises some interesting moral questions about sport fighting.
The ufc is a brand in the sport of mma. What the hell is the original poster talking about? The brand is hurting the sport. This is true. Is this his meaning? Someone explain to the small child who started the tread that there's a difference between a sport and a brand on a canvas.
I agree. In every bar-room brawl I ever saw when the two combatants were somewhat close in size and strength the fights always seem to end up on the ground. That's where a background in MMA would give you a huge advantage. If the guy starts biting you just start applying submission holds and chokes with greater intensity. You'd probably cripple or kill the guy as you be desperate to stop his biting or eye-gouging at all costs.
