Your biorhythm this month

Biorhythm theory, popular since the early 20th century and much loved in Thailand as the “monthly life graph”, says three cycles begin on the day you are born: physical (23 days), emotional (28 days) and intellectual (33 days). Each rises and falls like a wave, and the days when a wave crosses the middle line are called critical days.
