Hair or dread-locks, like skin, is an extension of the nervous system, it can be correctly seen as exteriorized nerves, a type of highly evolved 'feelers' or 'antennae' that transmit vast amounts of important information to the brain stem, the limbic system, and the neocortex.
The mammalian body has evolved over millions of years. Survival skills of human and animal at times seem almost supernatural. Science is constantly coming up with more discoveries about the amazing abilities of man and animal to survive. Each part of the body has highly sensitive work to perform for the survival and well being of the body as a whole.The body has a reason for every part of itself.
Not only does hair in people, including facial hair in men, provide an information highway reaching the brain, hair also emits energy, the electromagnetic energy emitted by the brain into the outer environment. This has been seen in Kirlian photography when a person is photographed with long hair and then rephotographed after the hair is cut. When hair is cut, receiving and sending transmissions to and from the environment are greatly hampered. This results in numbing-out.
Information about hair has been hidden from the public since the Viet Nam War.
When questioned about their failure to perform as expected, the older recruits replied consistently that when they received their required military haircuts, they could no longer 'sense' the enemy, they could no longer access a 'sixth sense', their 'intuition' no longer was reliable, they couldn't 'read' subtle signs as well or access subtle extrasensory information.
