Well, my interpretation is no more valid than anyone else's, but I would say in terms of medicine, people want to take control of their own lives, and ironically they seem to think that they are taking control of their lives more by using so-called complementary or alternative medicines than by using orthodox medicine. In other words, they think it's a statement of originality and individuality. To you and me it seems self-evidently ridiculous, this homeopathic medicine. It is so preposterous, and yet some people I know and respect insist on believing it.
