I take it you're predominantly inattentive (you omit the letter H). I see on the ADHD web sites they always advocate exercise, and I dismiss it out of hand every time as something I don't think would apply to me. I tend to think of the typical /r/ADHDer as being quite different from me, and not someone that I would even like, really.
So you're saying that that stuff applies for inattentives too?
