You intuitively know why you should bolt your doors when you leave the house
and add some sort of authentication for your smartphone. But there are lots of
digital entrances that you leave open all the time, such as Wi-Fi and your cell
connection. It's a calculated risk, and the benefits generally make it
worthwhile. That calculus changes with Bluetooth. Whenever you don't absolutely
need it, you should go ahead and turn it off.
