I have ADD (I can&#x27;t stand the H in ADHD - I&#x27;m <i>not</i> hyperactive) and I can spend hours and hours in front of a computer programming. I can also spend a hell of a lot of time doing laps of the pool for some reason.<p>I always find it ironic that it is my intense <i>concentration</i> that undoes me, the attention is ripping my mind away from the task I&#x27;m doing. Everything else seems to be a distraction, and that is <i>intensely</i> irritating.
