As if we needed further evidence that mobile devices and walking don't mix, a distracted teenage girl on a cellphone recently ignored warnings and plunged into a sinkhole in China.

As the young woman proceeded down the street, she failed to notice caution blocks on the sidewalk and blundered directly into a 20-foot sinkhole. But, to be fair, there's not much to indicate this is a dangerous area. Roping it off probably would have been a good idea.

A cabdriver saw the girl fall and rushed immediately to her aid, but the crumbling sidewalk trapped them both. See? Texting and walking can hurt those around you too.

Fortunately, firefighters rushed to the scene and rescued both people, neither of whom were seriously hurt. We bet neither will look at a cellphone the same way again, however.
