This is just about the coolest thing I've gotten for myself in a long time. It's a gadget you wear on your arm to measure your activity day and night. Then you can download it on your computer and get all kinds of neat statistical information on calories burned, calories eaten, and even the efficiency of your sleep cycles. These things are more commonly called Bodybuggs, but the one I have is called GoWear fit ...though it's made from the same company, is virtually identical, and has the bonus of being a bit less expensive.
Speaking of...it isn't cheap. This little goober costs about $150 plus a $7 monthly subscription to the website that crunches the numbers. I think it's worth it. This isn't a pedometer or heart rate monitor, it actually measures how you move. So far, it appears to be scary accurate. I'm hoping that this will be a big help in getting a handle on what I do for weight loss and fitness....rather than just kinda guessing at what I do and what I need to do.
