A friend and I used to walk our dogs together every day and when I moved she said she had to go back on her blood pressure meds because she didn't walk as far or as fast without me. It's too bad that doctors don't "prescribe" a half hour of somewhat brisk walking daily - for various reasons. Simple walking also compared favorably with Zoloft for depression in a Duke University a while back, for instance.

I joined a weight loss group last year and was rather shocked to find that most members do no form of exercise and ALL of them still eat sugar! Including the diabetics.
