I'm shocked, kids that young... they should be promoted to like physical activity, but like that... that's insane, to enter MMA a person should at least be a teenager with the concept of when to use it, how to control yourself, and keep yourself from using it in an un-needed situation, I personally want to go into MMA, I'm 16, but still age 3? that's nuts, They may be avoiding video games and other bad things, but they are putting themselfs at to high a risk and there will often be at least 5 people who fight outside of the gym even though they're taught not to, it's just how kids are.
