According to all of the lists online that  describes the "symptoms" of ADHD all four of my kids match every single symptom. In other words, they’re normal.

ADHD for some odd reason exists only in the US where "diseases" like that can be extremely profitable for "experts" who diagnose it, and pharmaceutical companies who sell the narcotic prescibed to "control" it. It also seems "educators" who don’t want to have to deal kids who aren’t drones, love it as well.

I’ve dealt with ADHD diagnosed kids and they generally tend to act off, at first, until they find out that I have absolutely no intention of letting an invented "condition" be used as an excuse for their bad behavior. Miraculously, they start behaving themselves once they realize that I won’t go along with the farce.

It’s sad that the link you provided show what great things high energy people can accomplish when they learn to control their energy. Drugs are not control. How many people would have been great had they been allowed to learn to control their own energy rather than being drugged?
