What are Biorhythms? Every one for no apparent reason, goes through periods of good form, good self-control and periods when the mind is particularly clear. Conversely, there are also periods when one is unable to concentrate and the mind is confused. The reasons for these fluctuations remain unknown. It is possible that the explanation lies in the Biorhythmic Cycle.  The theory states that human activity goes through regular high and low periods. As if it were initially set up for all time, based upon three different rates: 23-Day Cycle For Physical Strength And Endurance 28-Day Cycle For Emotional Activity 33-Day Cycle For Intellectual Activity       Reading a Biorhythmic Cycle. Each picture on the screen shows three separate curves, marked P, for Physical rhythm, E for Emotional rhythm and I, for Intellectual rhythm. Depending upon the day of the month, the curves are either above or below the horizontal axis, which represents the mean level. The positive phase of each curve is above the axis and the recovery phase is below the axis. Biorhythms may therefore be used to forecast whether one will be in good or mediocre form, on a given date.   Below are three of the most poplar Biorhythmic sites.
