Sukothefox hit the nail on the head. As having been recently diagnosed with ADD, I did my research on the ailment, and there's an overwhelming consensus from professionals that the disorder is overdiagnosed to an extreme level. Far too many children nowadays have been labeled as having this disorder when the reality is they're just children - they're supposed to be hyperactive and fidgety and constantly looking for things to do.

Honestly, unless you're talking to a professional well versed in what ADD/ADHD actually is, you can bet your sweet behind that a significant portion of the people you meet claiming to have been diagnosed as such have been misled.
