Periods of man's life

For a long time it was noted that man's life flows no uniformly. It is tracked in it a periodicity of different processes, an availability of the turning and crisis moments, qualitative jumps. Thus the periodicity of life process can not be reduced to a circling when we come back to the initial point and most likely resembles the spiral motion when as though there is also returning but each time at the new level.

Fibonacci's regularity is tracked already at the embryonic child development, which is terminated in the normal conditions for 266 days after ovule's fertilization. The chart of the embryo mass growth in depending on age has some fractures corresponding approximately to 24, 100, 200 days. These fractures characterize different phases of rearrangement in the embryo development. In the age of 24 days there is a passage from the cell-like development to the organism regulation mechanisms; in the age of approximately 100 days the period of rearrangement ends and there comes the phase of the steady development of the embryo organism; for 200 days the formation of all child's organs is terminated and the birth of the child after that term does not eliminate his further normal development.

Let's consider how it is possible to express through the golden proportion all indicated critical points in the embryo development. For this purpose we remind that some value can be divided by the "golden section" in two ways, by the golden proportion 1.618 or by the square of the golden proportion 2.618 or even by the cube of the golden proportion 4.236. If the number of 266 (the period of embryonic child development) is divided by the square of the golden proportion, we get the number of 101.6, which corresponds to the critical point in 100 days. If the cube of the golden proportion divides the number of 101.6, we get the number of 24, which corresponds to one more critical point of embryonic development (24 days). At last, the interval 266 - 101.6 = 164.4 divided by the golden proportion gives number 101.6 that corresponds to the third critical point (200 day).

The interesting information about periods of man's life, connected with Fibonacci and Lucas numbers are given by Nikolay Vasutinsky in his book "The Golden Proportion" (1990) and by Eduard Soroko in his book "Structural harmony of systems" (1984). The essence of their conclusions is the following. Critical man's ages correspond to the following years: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and all man's life can be divided into 7 periods: about one year corresponds to infancy, 1-8 years to childhood, 8-13 to adolescence, 13-21 to youth, 21-34 years to second youth, 34-55 years to maturity, 55-89 years to old age.

In Vasutinsky's opinion, life periodicity of woman is subjected to Lucas number: 1, 3, 4, 7, 11, 18, 29, 47, 76, 123. Shift of age intervals for women is explained more by girl's forwardness.

Seven stages of man's life determine seven main kinds of man's activity from physical growth and maturing up to a psychological and social formation. Up to ending of his growth (21 years for men and 18 years for women) the man physically matures, is trained. Then he starts his labor activity. Three qualitatively different kinds of man's activity determined by physiological and psychological organism condition correspond to three fundamental periods of his life: 21-34, 34-55, and 55-89 years. The youth period (21-34) corresponds to upsurge of physical and intellectual capabilities of the man. The main achievements of the outstanding scientists and artists happen just for this life period. In the mature age (34-55) it seemed in a heyday of forces, there comes overwork as a result of perennial activity, depression and apathy, the nervous failures become frequently, it is lost business grip. The age of 55-89 years is a time of philosophical understanding of life, summarizing, a time of revaluation of values, waiving of excesses, looking up of the "eternal truths", the "eternal values".

Apparently, there are the "crisis, turning" years and there arises the organism rearrangement not only for children, but also for adult persons; such "critical" years are: 21, 34, 55. Just theses "critical" years determine the life way of the adult person. And if the person leave outs these three qualitatively different periods, does not overhaul his life pursuant to the organism rearrangement, then he commits violence above itself, injures psychics, creates a stress situation and in the issue reduces his life.

After each "turning" year the person varies, he passes in the qualitatively new condition, is as though born anew. Recently in the press there appeared the reports about "epidemic" of the chiefs of mean and basilar links of English corporations. In the blossom of forces, by reaching 38-40 years, they suddenly cool to activity, run into depression. Service stresses, perennial overwork are considered as the cause of these crises. And it is not incidentally, that this "epidemic" starts after the "stagnation point" in 34 years. The person enters the new stage of his life that demands on the life mode corresponding to this change.

Maybe, it is not incidentally that many Japanese firms dismiss of their employees after achievement by them of age just 55 years. The stage of the old age begins after 55 years, the person should be rebuilt to the new labor and rest mode; the person can continue to work, but already in a new quality, it is desirable pursuant to his non-realized capacities and aspirations.

Seven person's time stages are his seven different life's given to the person by the Nature. They are various on the physical time: the first stage lasts physically one year, and the last one (55-89 years) lasts 34 years. But the biological time is identical for these stages and the first stage (till one year) lasts biologically as much as the last stage (since 55 till 89 years). The biological time reflects the speed of different processes flowing in the person's organism. In process of the organism ageing the speed of metabolic processes in it is reduced. Therefore also there is a sensation, that with the age "the time runs faster" because the person estimates a time not biologically but physically.

The conclusion about slowing down of the own biological time and acceleration of the physical time of the person at his aging is confirmed by experiments. Is was proved, for example, that with the age increase the healing speed of wounds is reduced and with the age the tired person restores his forces slower.

The Byelorussian philosopher Eduard Soroko supposes, that Fibonacci's peculiarity of the time development is inherent not only to the person's organism, but also to all self-organizing systems, in which the exchange time processes have irreversible nature. It falls into to animal organisms, populations, ecological assemblages and even to social systems. Soroko makes the supposition, that the historical process of social formations is deployed in time pursuant to the laws of Fibonacci growth, passing from "childhood" to "adolescence", "youth", "maturity" etc. And if the person organism passes the "qualitative jumps", the "epicenters of physiological revolutions", the similar jumps ("historical revolutions") should be tracked and in development of public formations.
