Biorhythms are a method of calculating human cycles based on mathematical functions. It "works" on the principle of sin waves denoting high, low and critical times in one's life. Biorhythms help in predicting future areas of trouble and difficulty (denoted by the "critical day"). For more information on Biorhythms, visit the Biorhythm FAQ.
