after hours: biorhythms
According to ancient Japanese theory our lives run in continuous cycles starting from our date of birth.
There is a physical cycle of 23 days, an emotional cycle of 28 days and an intellectual cycle of 33 days. Each cycle is divided into two phases, an active (high) phase and a passive (low) phase. The changeover days are regarded as critical as they are times of transition.
