I think I get that. I'm nowhere near as active-oriented as you are, but I get antsy when I've been sitting too long. I've started to "allow" myself to take a quick turn around my office building whenver it gets like that, just to let a little of that energy out. And I'm kinda glad there's not enough chairs in the conference room for the full project team, so I've taken to showing up late enough to have an excuse to stand for the whole meeting. Otherwise I sit in front of a desk all day, and I'm starting to realize that it sucks. I even get the running thing. I hate it and I have asthma, but the idea of jogging is starting to appeal to me. *twitch*
