BioRhythms - Version 2.0 Have you ever felt the ups and downs in your life? Do you know that these ups and downs depend on imaginary lines, called Biorhythms? These lines, when plotted, look like sign waves. They start at zero at person birth and go up, then down and up again. There are three of them: physical, emotional, and intellectual - and they all have different period. When, for example, the physical rhythm goes up, the person feels better physically fit, whereas when it's down, there's the highest probability to get sick. This application plots all these lines for a given period of time, given a person's birth date. Full online help is provided.
