I got a "Fitbit Force" as one of my Christmas presents. It functions like a computerized pedometer, really. I don't know how truly accurate it is - I haven't calibrated it yet, but I did some treadmill running today and it seemed to match up with the treadmill mileage pretty well.
Anyway, I've been surprised to see that I'm normally walking about 5 miles a day. I knew that my commute, and my dog walking, etc., had me walking over a mile a day. I would have guessed 2.
But 5 was a surprise.
Could it all be lies?
