BIORYTHEMS

   a fad of the 1970s NEW AGE MOVEMENT which sought to find links between human emotional changes, physical well-being, etc., and a rhythmic cycle in nature. The idea goes back to a nineteenth century physician Wilhelm Fliess whose work was popularized by George S. Thommen in various books published in the late 1960s and 1970s. There seems to be no scientific basis for this view and it is rapidly loosing popularity through its failure to really help people cope with living.
