One of the many fads in the 1970s was Biorhythms. Like most successful pseudoscientific theories, the notion of biorhythms has a basis in scientific fact, to the extent that many biological processes are cyclic. But the notion that a set of phased monthly cycles starting from the moment of birth and continuing through a lifetime, unperturbed by any trauma, has more in common with astrology and numerology than any kind of understanding of the human body or mind.
