I rely on my glasses every waking moment of the day. I can barely read a book six inches from my face. Without two simple circles of glass set in plastic on my head, I almost certainly would have stumbled blindly in front of a car or a train or some other way of coming to a gruesome end.

We don't usually think about gadgets as saving our lives, but that's probably because they're so pervasive. The gadget doesn't have to be new – we humans been inventing things for thousands of years after all. Has a piece of technology ever saved you or someone you know?
