My theory on ADD is that's it's being electronically driven--and that kids' brains are evolving in more ADD fashion because of the earlier and earlier fast-moving electronic interaction. I've found this to be true in several kids I've known since infancy and then seen differences in others who weren't exposed to so many bits and bytes of electronic media when their brains were forming neural pathways early on. I'm convinced this has an effect. Someday I'd like to be able to prove this theory.
