Dammit this seems to be popular. I wonder if it's reltaed to the food intake somehow? You know, they've said that about childhood ADD and ADHD. I'm sure that's not all it could cause.
I've often wondered if food has something to do with it too. When I was a kid it was a rare occasion for someone to go through it but now just look around and I bet 1 out of 3 people you see deal with it. Food nowadays is so full of crap to make it grow faster, produce more, and processed for maximum profits I wouldn't be surprised it has an affect.
