I know there are varying opinions on how old a kid should be before starting martial arts. I have a 7 year old son who is very ADHD. I have read some medical journals that really promote martial arts as a way to control a childs attention and compulsions. However, I don't want him to get burned out on it by the time he is 12 or 13. I started martial arts when I was 12. This is something I have always wanted for my son, but I want him to stick with it. It has always been a part of my life and I want the same for him. Any opinions on the subject is greatly appreciated.
