Walk the line

It comes as no surprise (to me, at least) that humans can’t walk in a straight line unless we have an external guide. We just end up walking in circles.

It turns out, no one is really sure why this happens but experiments on walkers, drivers and swimmers have all found the tendency to circle back on ourselves despite us thinking that we’re maintaining a steady course ahead.

Which makes one inevitably think: who is my guide?
