I've developed the best way to keep myself from falling asleep when I get drowsy in the mid afternoons after lunch, especially on dark, rainy Fridays. I do laps around the building. When I worked at Coke, I'm certain that's all Gary Paisley, our division VP, ever did. He would just wander around the floor and peek in at what you were doing so it looked like he was just keeping tabs on everyone. In fact, I don't think he cared at all what we were doing, he just did it to keep up appearances and because when your boss's boss's boss comes to see what you're doing, it's intimidating. Needless to say, I'm nobody important at GD (yet), and therefore not intimidating (though maybe scary ;) ). So instead of making laps where people see me, I'm doing them up and down the stairs. I figure it's better exercise than staying on a single floor, and I'm not disturbing anyone either. My office is on the 7th floor. So I'll walk down to the 1st floor past the cafe, head outside through the smoking area for a breath of "fresh" air and a nice view of the lake, and then go back in the other door. Then I walk back up to the 7th floor. It's remarkably invigorating. Gets the blood flowing again to combat the drop in glucose levels. So rather than snacking on sugar-heavy things, I'm going to start mastering 6 flights of stairs (each way) for a 10 minute exercise detour every afternoon around 3 pm. It's healthier and I suspect more effective, though substantially less tasty, than candy.
