How bad of a beating would it take for you pros to give up MMA.
If you took some strikes to the face like Scott Morris did in UFC 1, would it make you quit?
would only tap out to a joint lock, which would cause serious damage, where i couldn't fight again or would be a long road to recovery. But im no Pro so maybe if i was in the ring i might change my thoughts, lol. Guess it depens what mind set you go into the fight with!

MMA all together, would have to be a serious injury, where i was risking doing more long term damage if i continued
