I dunno, theres sometimes a mental part to being able to take a hit. I got hit in the eye in a fight with my glasses and it bent the frame and popped the plastic lense out. It hurt but I was too mad to care. he started backing away from me taking reaching swings but I wanted to KHTFO. He took me to the ground and wrapped me up and had he not pulled off of me and left me alone when he did, I'd have F'ed him up bad.
sometimes you just gotta not care that you have pain. But hey we'll see cuz the only way to find out is to wait till they mix it up in the Octagon.
