Haha interesting. With martial arts training, all my fidgeting is controled and precise, but I'm always moving definitely. I might be doing movements or energy related stuff that can't be noticed though.I was diagnosed as having ADD specifically because my biggest problem is the lack of attention. Everyone with ADHD and ADD is hyperactive in some way, which is why the "ADD" label is disappearing. People with ADD are still hyperactive on the inside, it just manifests itself in a different way. I can control myself enough to sit still for a while, but I still squirm, fidget and eventually drift away.
I honestly don't see the difference.
Are you saying ADD and ADHD, the only difference is whether other people can see your physical body parts moving?
