Here's a good study that gives us some clear direction on what to do. The New England Journal of Medicine reports a study of over 700 non-smoking, retired men and the effect of walking on reducing the risk of death.

The study found regular walking, of more than two miles a day, reduced the mortality rate by about 50%. Also,.......the more the men walked, the greater was the reduction in the mortality rate.

More evidence of the value of exercise, even if it's low-intensity exercise.
