Research is continuous on the effects of minerals found in the earth on the body and psyche. I often used to encounter New Agers who were so happy that they were disconnecting from the evil mundane universe and that they were living in a gentle high where nothing really seemed to matter. They were always chagrined when as an Elder being approached for comment or advice I suggested that they take a zinc supplement. Their symptoms were not those of a spiritual high, but of a zinc deficiency.
