While back, I posted a piece and link about a woman who was jogging with her iPod playing music who was killed by a falling tree limb in a park. Police allowed as how it would have made some noise, the breaking limb, but that the jogger couldn't hear it and it got her.
In Portland recently, a young woman walking next to the MAX train tracks, wearing a hoody and with her iPod buds in her ears apparently didn't hear the train and stepped right in front of it. She died at the scene.
And now there is this. Guy jogging on the beach at Hilton Head gets hit and killed by a small plane whose propeller came off, requiring that the pilot make an emergency landing.
The plane was gliding and thus probably pretty quiet, but you have to wonder if the jogger might not have been more aware of his surroundings if his hearing wasn't occupied.
On the tree limb post, "Paying Attention" back in August of '09, I allowed as how I thought being out in public and prey to traffic with your hearing blocked was a bad idea. Listening to your music so that you couldn't hear the big truck about to run you down? Not a survival characteristic.
IPods are dangerous. Keep it in mind.
