We all know that texting while driving is dangerous and now, as this video shows, we know that texting while walking can be pretty dangerous too.

A reporter for Canada's CBC News was doing a live report outside an office building in Ontario.  And in the middle of it, a woman in the background was walking and texting - and fell down a set of stairs.

It was just three concrete steps, but she landed pretty hard.  After laying there for a few seconds, a few people who saw it happen ran in to help her, but the reporter seemed to have no idea.

Thank goodness she wasn't chewing gum too - things might have gotten a lot worse.
