NPR's always interesting Robert Krulwich posted a great report on why people can't walk in a straight line from point A to point B without visual cues. Usually gimlets are involved in my case, but even sober, it's likely you will end up going in ever-tighter loops. Benjamin Arthur's beautiful animation alone is worth checking out.
