Karin gave me a Garmin Vivofit for Christmas. It’s one of those little wrist-mounted activity trackers. Being a Garmin, it fits in nicely with the fitness gadget ecosystem I have going already (running watch) and tracks my steps and sleep… or at least how much I move around when I sleep. It looks like it’s going to form the core of yet another step-up in my self-quantification efforts as we move into 2015. Turning everything I do into a number… does that make me more aware of what I do and thus healthier? Or does it just make me neurotic? We’re about to find out, I guess.
