A company that I worked for a few years ago went through the fitbit rage. They offered to buy me one, but I declined noting that I don't need another appliance to tell me I am fat. Or how little I do. For all I know it was reporting to them on my actual activity. Why do you think I work from home?
Actually I do track my steps on my (deeply embarrassed) I phone. But only when I am out of the house, otherwise my phone stays in one place whether I am moving or inert. I keep track of the dogs exercise that way, can't have him getting fat too.
It is almost 20 years ago that I decided I wasn't ever going to wear a watch again. I've managed to keep that promise, and I certainly don't intend to break it with something specifically designed to report how poor my shape really is.
