The reason why native Indian American Men have long hair is almost supernatural
2 They lost their tracking abilities because of haircuts
Those selected were documented and made to undergo the rigorous disciplinary methods of the army which included shaving off their hair. It was then that army authorities found that the Indian recruited were mysteriously losing their tracking powers without plausible explanations. Even their field performances deteriorated.
The older Indian recruits then stated that it was their military haircuts that were causing their problems. After getting a haircut they found they had lost their abilities. The military institute then decided to carry out tests and research to see if there was any measure of truth in such a fantastic claim.
