NatCapVidMo Day 22: Why Can't We Walk Straight?

A friend tipped me off to this fascinating story on NPR: Why Can't We Walk Straight? I chose to caption this for three reasons. First, I thought the animation was beautiful and it was the sort of video I wouldn't mind watching the four or five times it takes to go through the captioning process. Second, I thought it was strange that NPR didn't caption it, even though they offered a transcript for the audio link from Morning Edition at the top of the page. Third, I've got a simply terrible sense of direction even when I'm not blindfolded, so I like to think that my frequent habit of doubling back on myself and turning in circles when trying to find my way in an unfamiliar place is just a natural extension of this apparently inborn human tendency to walk in spirals, circles, and loop-de-loops.
