George Carlin had a classic stand-up routine about bad drivers: The car in front of him had its turn signal on for miles and miles; then he realized that the car's blinker wasn't stuck; the driver was simply going around the world to the left!

If you're someone who's stuck in one position for long periods of time (86 percent of American workers sit while working) and you're overweight, you're at risk for obesity, Type 2 diabetes, heart disease, dementia, and a lousy sex life. You know what you need? A good stand-up routine.

New research from the U.K. found that for overweight women at risk of Type 2 diabetes, simply standing up and moving around a bit every 30 minutes significantly reduces blood glucose levels. Even a little effort to change positions has huge benefits.

You know we want you to do more exercise than that, but we know how hard it can be to start a new exercise routine.

So to take this first step to health: Assign a stand-up routine to office buddies. Sue gets 9:30; you take 10; Fred, 10:30; and so on. Each person shares responsibility for getting colleagues to stand up and move. After doing it for a week, you'll all be more alert and have more energy.

And maybe one of your buddies will become a true health buddy once you all start seeing the benefits you get from this stand-up routine.
