Oooh I was having this same conversation today with a lady at work! She wore a pedometer and found out she does 11,000 steps a day! Not bad! I reckon I do about 10....... 10 steps... not 10,000!
I found a flaw in the pedometer system. The other week I decided to see what would happen if I walked backwards for a day. My pedometer went into negative numbers and I put on a stone. :o(
