Firstly, I cannot believe that no one has commented on this article yet. I damaged my shoulder some years ago playing football. Sinse then I've been weight training to preserve good health. It has now been about 17 years sinse the injury. In the past 2-3 years I foolishly stopped training due to work commitments. I come to train again about 6 months ago & cutting a long story short I was told by Doctors & specialists that my joint was worn away due to arthritis. I've been a fit person all of my adult life and this was a overwhelming dissapointment which was out of my control. I still refuse to accept it. However I'm now 32 and keeping fit and after seeing this information, I intend on making further inquiries. There is possible hope after all.
