According to biorhythms theory, our lives are affected by three primary cycles: Physical, emotional and intellectual. The cycles start at a middle point at birth, and then go up and down from this point at different rates throughout our lifetimes. Some people report that they can improve the quality of their life by monitoring these highs and lows.
