arthritis and muay thai

I hear ya crazy Joe, I was never pro but skated and snowboarded for years and have pains and twitches and friends of mine who were sponsored had to stop due to knee injuries, etc. And I've heard of some of the nastiest injuries coming from pro snowboarders, neck, knees, back, etc.

I've skateboarded for yearssss too,I wonder which was worse,I suppose its a bad combo when ya think about it
