Wow KZL!! Karate??? For real? Not combatives, but karate? You sound like you are headed for sure back to the real world of no limits. That would be cool. So far, my surgeon has not said no to bunny hill skiing 6 months out from surgery, which would put me into January 2011. I know I would take it easy.
You have been golfing though and had no ill effect. Maybe the stretches of Karate would be helpful, although the high kicks and potential for strikes to your back could be risks I would sure run by the doc first.
You are an amazing font of improvement and one for us to look up to with all you are achieving! Good luck on the college work!
