The problem with the medicine men is that they perform a rol of magic healers but with an official Title confered by society througt the goverment. Because of their titles they are simple agents of the only one Medical Science but according to the tradition they really act as magicians saying whatever nonsense to their patients who must believe it because their are the doctors who speak in the name of the official Science. So we have father and son saying to opposite thing about milk to the same people against what the official Science says but with the protection of its official titles. Does it not crazy?????.
