Repair is mandatory since I have had 3 episodes when my waist expanded 11 inches overnight combined with a 90 % loss of energy.
Three days later I would be almost back to normal but none the wiser as to what was causing it. When I find out exactly what kind I have I will still wonder how I could have done some of the physical feats this year without further injury. Lucky I guess.

Some of you should write the book "Abs of carbon fiber mesh"
When people have had carbon fiber to repair ligaments and tendons, the carbon was so strong that the bone would break before the tendon would.
