My old fitness tracker’s days are coming to an end. It is still working but it has been getting increasingly glitchy over the last year. I’ve known that it has been on borrowed time, but I’m still sorry to see it on its way out. As much as it has had a couple of stripes through the screen for some unknown reason – they’re not consistently there, only mostly – and the brightness has been fading substantially, I’m accustomed to the way it works and how it functions in my life.
