It is still unknown why people go astray, and begin to walk in circles

For centuries it was believed that the reason for this lies in the peculiarities of circling our body, namely the fact that we have one leg slightly shorter than the other usual. However, in reality it is not. Experiments have shown that spiral motion - the universal quality of wildlife. When people are walking blindfolded consistently perform spiral movement, as, indeed, and during the voyage or flight. Animals exhibit similar behavior, including microscopic creatures such as amoebas. The reason for this is unknown. There is speculation that the spiral motion is due to the Earth's rotation, the electromagnetic field, or with the mechanism of the brain that determines the direction.
