In the workplace, railroads and airlines have experimented the most with biorhythms. A pilot describes the Japanese and American attitudes towards biorhythms. He acknowledges, researching his pilot logbook, that his greatest errors of judgment occurred during critical days, but concludes that an awareness of one's critical days and paying extra attention is sufficient to ensure safety. A former United Airlines pilot and user of the Biorhythms for Windows program confirms that United Airlines used biorhythms until the mid-1990s, while the Nippon Express air freight still used biorhythms.
Charting biorhythms for personal use was popular in the United States during the 1970s; many places (especially video arcades and amusement areas) had a biorhythm machine that provided charts upon entry of date of birth.
Calculation
The equations for the curves are
- physical: sin(2πt / 23),
- emotional: sin(2πt / 28),
- intellectual: sin(2πt / 33),
- intuitive: sin(2πt / 38),
where t indicates the number of days since birth.
