I've been growing my hair and beard for 2 years now because it feels right to me at this point in my life. I do believe that hair is in fact an extension of the nervous system, and as many indigenous cultures believe, that it functions as a psychic antenna. Although, I find the alternative view of the Tibetan Monks that shave their hair interesting, as they say it makes you more susceptible to psychic attack. "With great power comes great responsibility," I suppose. Whatever the case may be, I love my hair.
