Last night, Michael Venom Page crushed the nose of Derek Anderson with a kick. Anderson staggered for a second, then charged in to keep the fight going. I'm always amazed at the damage that some fighters receive without showing an ounce of pain. Yeah liver kicks have that slight delayed effect. It's incredible and kind of funny when a fighter can take elbows to the face no problem but an eye poke drops them. Groin strikes obviously. Leg breaks duh. And I understand the effects of adrenaline and everything, but I wonder: Do professional fighters have to learn/train pain tolerance or is it just that a person with a naturally strong tolerance for pain is more likely to be a successful fighter and make it to Bellator/UFC/etc.? I would love to hear from people who have actually competed but anyone can chime in of course.
