Have you ever worked in an office where they hand those things out? And then they try to have a "fun competition" to see who walks the most steps in a given day? To encourage physical activity and health? Yeah. You're not fooling anyone, employers. If you wanted your employees healthy and physically active, you would a) provide better health plans and b) not tether your employees to desks all day long. Human beings are built to be active all day long. Forcing people to try to partition off a small portion of their limited free time as "the time I move" is fundamentally unhealthy, and then using a wide array of tactics, from these pedometer things to pop cultural messages all over the frickin' place, to make them feel bad about not doing it, is just cruel.
Speaking of which, I think I'm gonna get back to running every day after work. It really does make you feel more human. And hell, it's warm enough.
