A Mystery: Why can’t we walk straight?

Try as you might, you can’t walk in a straight line without a visible guide point, like the Sun or a star. You might think you’re walking straight, but as NPR’s Robert Krulwich reports, a map of your route would reveal you are doomed to walk in circles.

It’s a mystery to me. But the animation is wonderfully done.
