Many years ago, I trained in Judo and sustained a severe shoulder injury after being thrown by my Sensei. I required surgery, and live with two plastic pins somewhere in my shoulder bone or rotator cuff. I love Judo, but I am afraid of ever sparring again or returning to Judo due to my experience. Moreover I saw a short clip of a Japanese adolescent who is in a permanent vegetative state from being thrown so hard in Judo. How do you deal with injuries? Do you come back to the sport or martial art that caused your injuries? I know boxers who needed handed surgery, and I myself have been knocked out during a sparring session in boxing. It seems like everything I love is too dangerous and risky to actually continue training in.
