most people in their 20's don't have the balls to get into boxing.....this is a true man's sport....mma..martial arts...easier to do....not as hard.......damage is not near as much.....no real "Tap Out" in boxing....and because you really need superior skill to excell at boxing most 20 somethings don't want to put forth the effort...they want what comes easy to them......and boxing is never easy.....
