I usually don't bother listening to more than a second or two of this windbag, but this piece has some merit. I've suspected that ADD and ADHD were being attributed to more people than they should, and according to this report, only a fraction of those diagnosed are genetically disposed to them. If you're being told you have ADD or ADHD, you might want to see if a change in diet and exercise will help.

There was a guy on youtube a while back by the name of Urgelt. He hosted a health webcam style show. It was really informative and covered such susipicions and issues analogous to them.
That guy has the largest, most elf-like ears I've ever seen.
