They should conduct drug test on this guy.  He obviously showed no sign of fear when getting many punches on his face.  He just stared at his opponent then relentlessly attacked without tiredness.  Any fighter would weave, duck, slip or step back when getting a combo on the face. I participated in amateur fight after I spared it all out for 9 times and I know exactly what a fight is: on the mat, the ring or on the street.
