Part of it I can understand, but then I start to get confused. Why wouldn't we be able to walk straight, even without a visual reference? Guess that's the reason for the study.
Why Can’t Humans Walk Straight?
A German research scientist named Jan Souman conducted an experiment that showed that humans are incapable of walking in a straight line. Souman blindfolded his subjects and instructed them “to try to walk straight for up to an hour.” Instead of walking straight, the volunteers walked in circles. The German scientist conducted the experiment in various locations, such as the beach and the Sahara Desert, but the results were the same.
Souman then tried another experiment, and this time there were no blindfolds. The results were different and a bit surprising. If it was cloudy out, the subjects walked in circles. When the weather was good and sunny, only one of the subjects was able to walk relatively straight.
So why does this phenomenon exist? Scientists don’t really have an explanation, and Jan Souman is still working on a multi-causal theory.
I can't figure out this one. Most of the time I couldn't walk straight was when I was under the influence of some alcoholic beverage. I wonder what my excuse would be now that I don't drink any more?
Coffee inside this morning. Rain may be lurking right around the corner!
