We Need to Get Off Our Butts
A new study confirms, Americans take fewer steps:

The study tracked the steps of 1,136 adults around the United States who wore pedometers for two days in 2003. The results were compared to similar pedometer studies in Switzerland, Australia and Japan. The data collected showed that Americans, on average, took 5,117 steps a day, far short of the averages in western Australia (9,695 steps), Switzerland (9,650 steps) and Japan (7,168 steps)....

The fitness gap detected by the pedometer studies is equal to about 30 to 40 minutes of walking each day. One mile of walking covers about 2,000 steps, researchers say. The health community typically urges people to take at least 10,000 steps a day to maintain good health, which is equal to about five miles of walking.
