Raamatus vaadeldakse erinevaid biorütme ja nende avaldumist erinevates inimsuhetes.

The author of the book hopes that the book should be of interest to those who are not indifferent to biorhythms, to those who hold it as a hobby and also to scientists who study biorhythms.
Although the biorhythmic factors' impact is usually modest, their influence is continuous - and this is what really matters. Infradian biorhythms determine our relations with other people and the society. We should always bear this in mind.
