A must-have accessory for anyone with a mobile gadget is a pair of headphones. Most smartphones and media players come with a free pair, and you probably have several of these lying around your house.
Headphones let you listen to your music or watch a movie on the go without bugging everyone around you - assuming you keep the volume at a safe level. That's great for tuning out noise and distraction on a bus or in a busy office environment.
Unfortunately, headphones can also block out important warning sounds like sirens and oncoming vehicles. I've run into this problem more than once on my morning jogs. Fortunately, I've always come away OK, and I've learned what parts of my route are OK to use headphones and which ones aren't.
Shana Buchanan of Minneapolis wasn't so lucky this last weekend. While wearing headphones, she walked in front of a light-rail train, was struck and killed.
This tragedy highlights the importance of paying attention to your surroundings, especially when wearing headphones. I have a few safety suggestions that everyone should keep in mind.
