I've known too many people who have had serious injuries from this sport. One colleague is now on permanent disability after a concussion he received while wearing headgear and practicing on a mat. Another friend has chronic shoulder issues that he can't seem to heal from after a couple bad rolls with a few overly aggressive sparring partners. I think for long-term health and overall fitness BJJ is a tough sell for most people.
