"Those poor guys probably forced into the ring" That's your first mistake. Nobody is forcing these guys to do anything. They enter competitions because they want to. Most have been training martial arts or combat sports such as karate, kickboxing, Brazilian Jiujitsu, and wrestling for a good portion of their lives. The enter an MMA (Mixed Martial Arts) competition, work their game against the other guy, then shake hands and go home. Usually they're back in the gym within a week, preparing for their next fight. And they love it. Most guys look forward to the day when they can make enough money to quit their day job and train full time. "break their jaws off" Haha... another mistake. The most common injuries in MMA are bruises and cuts on the face, maybe a broken hand or concussion. And unlike football and hockey players, when they get a concussion, they don't come back after a week because they're afraid of losing their spot. MMA has a better safety record than boxing, skiing, gymnastics, football, motor sports, water sports, and cheerleading. "making huge profit out of their misery" I cannot overstate this: MMA fighters do what they do because they love it. Yes, there are hardships involved. Yes, they get hurt and sometimes injured. But most of these guys could have any other job they want. Rich Franklin gave up being a math teacher to pursue this. Carlos Newton, MD, runs a geriatric clinic, and still finds time to fight. Nick Thompson took his bar (law) exam the day after a big fight, and continues to fight. The best quote I've heard for this comes from Phil Baroni: "[I fight because] I can't sing, I can't dance, and it beats working for a living".
