bull riding easily. Since the modern rules that are almost universally followed for MMA competition were instated, there has been less than 10 deaths due to training or competition. Even major injuries are less frequent than in other contact sports like football. Bull riders have a very small margin of error lest they be seriously hurt or worse. Plus the fact that in fighting you have a referee who stops things before your really hurt. I know about rodeo clowns and all of the help they have down in the arena but that is a very large, angry, animal, very unpredictable.
