Biorhythms theory
The Biorhythms Theory states that human lives move in predictable undulations involving three separate cycles:
✓ Physical - 23 days
✓ Emotional - 28 days
✓ Intellectual - 33 days
These cycles start at your day of birth and affect your daily life.

Critical days
Critical days have been described as full of danger and difficulty. They are days of flux and high instability. These are not days to fear but to perhaps be on guard. Critical days are not days when an accident will occur but are a time when you will be more accident prone. Just knowing that this is the case can prevent the accident or error.
