Zoom Zoom, I hear you! As much as I loved mountain biking, and as hard as it was for me to decide to quit, the decision brought a measure of relief. While it looks like my mountain bike crashes left some permanent physical consequences (neck) for me, I am very lucky compared to some I know of. CNS damage can be far worse than what I experienced. It is a great sport - but certainly on the edge! My problem last year was that I kept second guessing myself which didn't help the soft tissue damage that I am currently dealing with - I KNEW I should have stopped before I did but darn it, when it worked for me it was so much fun! In retrospect, it was a bit much to take on at 51-52 years old but I HAD to try it
