Biorhythms's theory tell that a man life, is ruled by three rhythmic biological cycles, that influence on biological processes for their relative attitude:

Physical
Emotive
Intellective

Each biorhythm oscillates between a positive phase and a negative phase, influencing the relative attitude strengthens and weakens.

Every time that the waveform crosses the horizontal center baseline, there is a critical day, which means that tasks for relative cycle are worsted than other non-critical days.

More biorhythm cross the baseline, in same day, most critical is that day.

The main purpose of examining biorhythms is to preventively know, critical, bad or good days for performing or avoiding particular life activities.
