Everyone knows this. Wearing your Bluetooth phone device on your head while not in use is like wearing a big fat earing that says, “I’m a pretentious goofball.” The Bluetooth headset, however much it set you back is not the status symbol you want it to be. It shows that your status is stupid.
At least you won’t get brain cancer. The wireless waves bouncing around inside your skull will echo forever before they find any gray matter.
