That's what people used to call a walk. People have known for centuries that walking keeps you fit, healthy and helps you sleep at night. But for many Americans, in our suburban-sprawl, get-on-the-highway-to-go-to-work lifestyles, walking is no longer an easy and accessible activity. I say it should be.

Even 10 minutes a day improves circulation. A quick walk can improve your mood, too. Yes, I know how jam-packed days are. I know there simply isn't time. But I say make the time. It's for your health and mental well-being.

So my gift to myself today is a walk. I hope to do 30 minutes. That's ambitious. But it'll also keep me fit. And that's worth a lot.
