Your grandfather experienced head injuries! And you still think that punching people is great?
Ralphy, I don't think you completely understand what fighting is at the professional level. It isn't all about getting in the ring and knocking some guy's or gal's brains out. It's a professional sport and should be respected for the participants that have invested so much time preparing for their matches and bouts. Fighting requires strength, endurance, intelligence and toughness. One has to be able to over-come the many injuries and be able to keep pushing themselves up one more rung on that ladder to achieve greatness. No one gets on a ladder on the top rung; it's a one step at a time approach. Thousands of hours of training go into becoming the fighter that they are.
I would agree that if a person is afraid of being hurt physically, then this sport is not for them.
It seems that pain is part of the problem in this "sport" for those who inflict it on others or on themselves while training...
Good question, Phil. It is supposed to be non-competitive but not all practitioners of yoga adhere to that. And when I observe some of the "stars" of the yoga world, I can't help thinking maybe it should be a sport because the flexibility, dexterity, balance and skill equals or exceeds that of any expert gymnast. But, of course, that's just the physical aspect. To answer your question, my instructor would probably prompt me to say "no". But I'd love to see it in the Olympics!
