Kids as young as six years old are participating in mixed martial arts. You can go to Youtube and find tons of videos of these kids fighting.

At first, it may seem really brutal for a couple of six-year-olds to jump into the octagon and go at it. I don't think it is. Kids start wrestling at age five. South Dakota Junior Football starts in 3rd grade, which would have kids as young as 8.

If it's a regulated sport, like any other, I don't really see a big problem with it. What do you think?
