The "mind" is the brain. Where else would you put it? Everything you experience and learn goes into the brain and gets processed to the best of it's ability. As far as ADHD goes, it is past on through the generations. I can see who has it and who doesn't. I know I do and I've had to learn tricks to deal with it, and still trying to deal with being a successful adult. Yes, exercise does help. It lessens the symptoms temporarily to help with concentration, but it's very hard when you have a task that requires you to sit still for several hours, or if you feel socially backyards, or you have impulse behavior like blurting things out, or doing risky activities. I do hope that they are able to diagnose ADHD with something more tangible and measurable. My mother suffered with it for years. She is a intelligent woman who always believed she was dumb because of the attitude that was placed upon her.

I wish people who make claims that this isn't real, do their homework and research this topic before opening theirs mouths. Remember, there used to be "idiot savants". Now it is diagnosed as "autism".
