I read a LOT of BLOGS and so many people DON'T have jobs and they go on and on about how they don't have money, so you are LUCKY to have a JOB. It is great that you have a teenage DD who can help with the housework and take care of getting herself to school. I read blogs from so many Sparkers who have pre-school children who require constant care and so they have NO time to exercise, etc.
Yes, I think pedometers are accurate. Lets say it jumps or looses a couple of hundred steps. So what? The important thing to me is that I am tracking my fitness goals and every step I take is more THAN WHAT I DID BEFORE I BOUGHT THE PEDOMETER!
