So true. 
My 2nd last comp I went to some guy broke his finger sideways, got it taped by a medic then rebroke it. He still lost, but I'm like my guy it's a cheap medal, don't you have work tomorrow? 

The last comp I went to the guy I beat later got choked out. I thought he had his foot broken but they were just trying to help him regain conscious by elevating his feet. Tsk tsk.  

 Lol yeah sounds like those guys feel a need to prove how tough they are. Def an ego based flaw. Like if your life is on the for sure bang out to the fullest but destroying your body to try to win an amateur bjj comp seems reckless and silly.
