Well, the analogy was good enough that you got the point.

I don't see how wearing a watch that gathers biometrics would be unhealthy. A small bracelet without any display would be fine with me. At the moment, I don't need this - I'm in my prime. But once I get older, I might benefit from having a small buzz on my wrist alerting me that I'm working too hard mowing the lawn, or whatever.

I'm also against a model such as the one you describe, like I have made clear in my post.
