Okay, so I'm minding my own business, sleeping peacefully, and the boom box in our spare bedroom suddenly starts blaring. It's not a radio alarm. There is no reason that it should have turned on. I never ever use this boom box. Spooky. So, I couldn't go back to sleep. I got up and got my tush out for an early morning walk. My HRM was hinky, but it was a different one that I haven't used in a while.
