These rhythms continue throughout life. These rhythms are called biorhythms and have been studied by experts in medicine and psychology. Biorhythms are now considered so important that they are used in labor management by companies such as JR and private railway bus companies. The cycle of biorhythms is as shown in the diagram on the right, but usually, it requires complex calculations and drawing to derive the biorhythms. However, with this "Masaki-style biorhythm meter," there is no need for complex calculations or drawing; you only need to align the four discs. 《Features of the Masaki-style Biorhythm Meter》 You can instantly know your past and future biorhythms at any time.
