Have you ever noticed someone talking to themselves, only to find out that they are not, in fact, insane, but just talking to someone on their bluetooth headset?Do you seriously need to be that connected to your phone so that you never, ever miss a call? Sure, it's probably useful in your car when you really need to be hands-free. But once you park - take it off! Face it - if you are wearing a bluetooth headset 24/7, it's because you want people to think you're cool. Period.
