I have a good family friend, who's father was a professional boxer. Look up Tony DeMarco. That is his dad. You guys should watch those old fights when they went for rounds and rounds until someone K.O.ed.
Did you ever watch swamp buggy racing? racing through the sippy hole was the best. or what about early ufc? I remember watching when there wasn't any weight classes. I even seen a guy go into the ring with only 1 boxing glove as a style
