Well, I ask because one of the students at my BJJ school asked one of the instructors.."When is the best time for someone to start BJJ?" To my surprise, the instructor said, the ideal age is 16+, but 14 is good also. Another guy asked why, and my instructor basically replied, because if you start at a young age, the chances of getting injured is high and it will carry on with you through out your adulthood. Starting at a young age (like 5-12) can also burn oneself out in the future, whether its physically or mentally. I was pretty surprised, because I thought: younger the better, but I guess not. What do you guys think, I mean after all..This is just one opinion?
