46% doesn't tell me a lot; people that already were avid exercisers probably didn't change, and of the remaining a good portion changed their approach! Much better than expected. Lifestyle changes are the hardest (dieting, stopping smoking/drinking, exercising). Question is how much change is seen, and what impact it…

My favorite one is the item that when I'm away from home it enables the mobile data plan and enables the pattern lock, but just as soon as it detects my home wifi in range and connects to it, it switches off mobile data and unlocks the phone.

I shop at Fleet Feet in Chicago.
