With 20 years of international Judo training, I am a professional and careful grappler. I have never left a significant injury in my path (except for a few in hard-fought official matches.) I get medical harm in some sessions, however, because the men are unreasonably competitive. But my clients always leave intact. Except for broken hearts, that is. Look at my travel schedules and you can see them all around the world, fractured in a million pieces.
