The manual has an impressive bibliography of books and articles on the theory of biorhythms. It says "Biorhythms
are defined as the different cycles your mind and body go through every day. There are three of them. A 23-day physical cycle. A 28-day emotional cycle. And a 33-day intellectual cycle. Your daily position in each of these
cycles has a lot to do with how you feel"
The analysis of a persons Biorhythms was fashionable in the mid-1970s. Kosmos produced several models of calculators for making the calculations in the 1970s, some also sold under the Radio Shack name. They are not uncommon so must have sold reasonably well.
