I for one find very interesting the path we chose when blindfolded.
And if, with no visual things to guide us, we think that going in a wibly circle is a straight line, then probably that is what our brains perceives as a straight line.
Or perhapse it has something to do with the fact that sight is what we use to identify our position and takeing that
away makes it hard to orientate.
It`s all very interesting.
