Even if you're not into long walks as a form of exercise, you might have traveled farther by foot than you ever imagined.
The American Podiatric Medical Association says the average person takes 8,000 to 10,000 steps a day. Those cover several miles, and they add up to about 115,000 miles in a lifetime -- more than four times the circumference of the globe.
So, think of the added benefits if you get off the couch and onto the road. You've already got a big head start.
