The iPod may not be as innocent as it looks. And there's something even more dangerous than the terrible music the person next to you is listening to. A study by medical doctors and one inquisitive teenager shows the iPod may interfere with the activity of cardiac pacemakers. No other handheld music players were tested. So the iPod joins a long list of electronic devices that may interfere with pacemakers. They range from microwave ovens (even if you don't stick your head inside) to radio transmitters.
Could we be seeing surgeon general warnings on iPods and their cousins?
