Trig graphs – how do you feel today?
Biorhythms are interesting. There is no science involved, and they should not be taken seriously.
I have added a section in the math site called Biorhythm Graphs. Check it out.
Biorhythms are interesting because they are examples of trigonometric curves with different periods.
For a skeptical analysis of biorhythm theory, see Skeptik’s Dictionary.

What baloney!
There have to be cycles in our emotions (a woman’s period is an obvious one).
But this biorhythm stuff is nonsense.

Mr. Bourne’s and others’ skepticism is justified in the sense that as mathematicians / scientists, they are unable to affirm that the sine curves would coincide with our actual biorhythms, so that we could derive advantage out of that. Whether it is trying to predict “ our future ” or the “ future prices ” in financial markets − they are equally mythical / truths / unknown / whatever ! Any way, that it is the realm of unknown, and that statistics is a science, medicine is a science, Laplace’s determinism is science, “ butterfly effect is a science ” − why not biorhythms and astrology are so ? This is so, because our life span is not enough to conduct a study, make observations on subjective rather than objective issues, formulate a hypothesis, undertake further study to prove or disprove the validity of that hypothesis to make a theory out of that. It is the complexity of the subject that precludes it from a scientific study [ by current definition of science ].

Thanks for the input, madhav. Actually, I’m inclined to believe in some sort of biorhythms, but not as per the graph above.
