ADD and Exercise
I'm fairly certain that my husband has ADD, although he insists that he does not. Apparently during his first marriage, his first wife made him go get tested, and he was told that while he was close to the diagnosis, he didn't have it. He thinks it's a made-up disease used by people who want to control others.
In spite of this, and in spite of our different temperaments, we have managed to learn to accommodate each other in most areas. The one area where we cannot find common ground, however, is exercise.
