I just read an interesting article about Native Americans and the Military. According to the article, during the Vietnam War Native Americans were recruited for tracking, they lost their tracking abilities once their hair was cut.
"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.
Hair 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.
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 .
Cutting of hair is a contributing factor to unawareness of environmental distress in local ecosystems. It is also a contributing factor to insensitivity in relationships of all kinds. It contributes to sexual frustration."
