Do you know?

A biorhythm (from Greek βίος - bios, "life" and ῥυθμός - rhuthmos, "any regular recurring motion, rhythm") is an attempt to predict various aspects of a person's life through simple mathematical cycles. Most scientists believe that the idea has no more predictive power than chance and consider the concept an example of pseudoscience.

The three primary biorhythm cycles are:

Physical: This cycle is 23 days and tracks your strength, health, and raw physical vitality.

Emotional: This cycle is 28 days and tracks the stability and positive energy of your psyche and outlook on life, as well as your capacity to empathize with and build rapport with other people.

Intellectual: This cycle is 33 days and tracks your verbal, mathematical, symbolic, and creative abilities, as well as your capacity to apply reason and analysis to the world around you.

The four secondary biorhythm cycles are:

Intuitive: This cycle is 38 days and influences unconscious perception, hunches, instincts and 'sixth sense'.

Aesthetic: This cycle is 43 days and describes interest in the beautiful and the harmonious.

Awareness: This cycle is 48 days and expresses ability to perceive own personality and individuality.

Spiritual: This cycle is 53 days and describes inner stability and relaxed attitude.
