A teenager who had surgery to remove a brain tumor made news when he also listened to his iPod during the procedure (well, while he was conscious). It reminded me of how I always listen to my iPod when I'm at the dentist; not having to hear the drill as loud saves me from having minor freak-outs.
It's not just the sound of my preferred music that I like, either; having something I'm so familiar with is comforting, and a great distraction if I'm enduring something painful or uncomfortable.
Most people use their gadgets to pass the time, but this use of an iPod is something I find truly valuable. What about you? Do you listen to your iPod at the doctor or dentist, or somewhere else uncomfortable?
