The exact juxtaposition of every group of curves of two persons reveals a relational agreement emotional and intellectual of 100 %.

In every position of the curves of a person with regard to another person, a ladder of compatibility which will indicate the degrees of relational ease of both persons involved (their respective levels of reception emotional, of sensitization, humor, availability, understanding, psychic plasticity...)

The glands endocrines " thyroïde, pituitary gland, suprarenal... " provoke physiological and psychological alterations. They influence more or less our state of mind, our humor, our dynamism, our reactions in stress, etc. , according to the capacities of our biologic phases.

So, between two persons of good agreement, when their cycles are at most or at minimum of their conditions, their relations will remain always good because their levels of understanding, the humor, the emotionalism, etc., will remain of the same value.

The biologic numbers are valid with the Gregorian calendar used nowadays. The number 1 is situated on October 18, 1582.

The synthesis of the cycles in question is 924 days. This period is the time when both cycles return in their point of departure. There are so 924 biologic numbers. The 925-th day creating a new number 1(obviously compatible with 100 % with all the others number 1).

NOTED: a good compatibility is not enough for being happy in couple. Do not forget the education, the politeness, the tolerance, opening of spirit, the respect for others...
The sexual agreement: the good emotional and intellectual agreement facilitates the sexual agreement. Nevertheless the physical, mental constitutions, the attractions dominate most of the time.

The more the average of age is high, the more the adaptation, the understanding, the tolerance, the compromises will be sometimes difficult. When the passion is past, it is at this moment that one knows if we are compatible.
A good emotional and intellectual agreement guarantees a happier life.

If it is true that the biorhythms were brought since the antiquity, it is only in 1960's when the scientists are interested.

Without forgetting Hippocrate, Aristote, Pline and others of the 18-th century, it is at the beginning of the 20-th century when W. Flies and H. Swoboda, discover, among the others, the biologic cycle of 28 days attached to the endoderme, "the emotional cycle ".

They also discovered the cycle of 23 days of the mésoderme ( the physical cycle).

Towards 1920, Teltscher determines the cycle of 33 days in the narrow report with the ectoderme and baptizes it " the intellectual cycle ".

In 1973, in New York, George S . Thommen publishes a work where he makes(does) the synthesis of these three essential cycles and demonstrates by the scientific observation, the influence of these biorhythms on the social plan.

Mendel's works in the last century and more recently of N. Pende helped in the understanding of all these biological mechanisms and the scientists recognize the fact that all the vegetables, all animals and all humans are steered by rhythmic cycles.

The researchers discovered the other rhythms of different cadences (of some fraction of one second at several years).

Only to quote Alain Reinberg and Jean Ghata at the origin of numerous works in this domain, here is

Ultradiens rhythms (from second till some hours):

Pouls (env. 1 dry.), respiratory cycle (env. 1 Mn), cortisol plasmatique (45 and 90mn), testostérone plasmatique (env. 90mn), sexual behavior (env. 8 hours).

Circadian rhythms and nycthéméraux (of several hours in more than a day):

Temperature (env. 24 hours), hormonal cycle, cycle of the sleep, food(dietary) behavior (env. 24 hours), Pouls-cortisol-testostérone and sexual behavior (also in period of about 24 hours(o'clock)).

Circamensuels rhythms (furthermore from day to several weeks):

Confirmation of the emotional and menstrual cycles (env.28 days), intellectual cycle ( 33 days), physical appearance(physics) ( 23 days), lunar cycle (29 days, 12 hours, 44mn and 2 , 8 dry) influencing the blood pressure.

Rhythms infradiens and circannuels (from week to one year):

Cycle of the seasons which influences our psychic and organic life. Temperature (env. 7 days and 1 year for the man and env. 30 days for the woman), cortisol plasmatique (env. 30 days for the woman and 1 year for the man), pouls radial nerve-testotérone-comportement sexual and food(dietary) (env 1an).

The physiological processes as the sedimentation speed of the blood, its volume, its pressure, its rate of calcium and phosphate, the number of white corpuscles, proteins, the fragility of capillaries, the metabolism and the endocrinienne activity join also infradiens rhythms.
