Although what you have gone through sounds like hell, remember you are alive. You came very close to losing your life and for that you should be very grateful you're even able to post this message. So if you're not able to snowboard again or even do major sports, you'll still be alive. I'm sorry for the ordeal you've gone through but glad you're still with us. I wish you the best of luck in a speedy recovery Quiet. Cheers
