Biorhythm comes from the Greek words for life and regulated beat. The science of biorhythm is concerned with the rhythmic cycles of physical, emotional, and intellectual life. These cycles have lengths of 23, 28, and 33 days respectively. During the first half of each cycle, energy is high. During the low period, second phase abilities, feelings, and competence decline. The worst periods are critical or zero days when the cycle changes from high to low or vice versa. During this period, the body seems to be in a state of flux and thus has a considerable degree of instability. A biorhythm chart can be calculated from one's birthdate. (CD)
