We have seen plenty of videos about people texting or talking on their phone while walking and inevitably doing something stupid because they weren't paying attention. This is different, this isn't a simple slip on the stairs or a fall into a fountain - check it out.

According to the Today Show, a young woman in China was too busy chatting on her cell phone to realize there were caution blocks on the side walk. Had she been paying attention she would not have fallen down a 20 foot sinkhole in the sidewalk. Thankfully rescue crews arrived quickly and retrieved her from the hole with no serious injuries. She got seriously lucky.

I don't care what you are doing - walking, biking, dancing, jumping rope...if you are incapable of doing more than one thing at a time, then don't. Put down the cell phone before you hurt yourself or someone else.
