Old public health guy's plea: Don't wear your headphones all the time

This is going to sound like just another old guy rant, I'm afraid. But it's not. Or at least that's not all it is: I propose that people stop wearing headphones when they are out in public.<br><br>Now I realize that I'm already showing my age and lack of hipness by calling them headphones. The correct term of art is at least ear buds, if not some name I don't even know. But you get the idea: those little speakers on a cord, usually white, that are crammed into everyone's ears as they walk around, sit on the subway or ride in an elevator. They drive me crazy.
