Four-agecat theory of humanhood in the 21st century

The complex science of humans require more general reconsideration of the human as a category of biological, social, cultural, ideological, creative, stereotyped, enculturated, socialized and emotional multi-personality, for example (the quality aspects can be increased). Isn’t it a paradox that today we still believe the age of 18-29 is emerging adulthood (e.g. Jensen and Arnett, 2012)? One of the results of globalization is that we have been moving not only toward gender egalitarian (Grøntvedt & Kennair, 2013; Bleidorn, Klimstra, Rentfrow & Gosting, 2013) but also toward age egalitarian global society. The main problem of psychological age theories is that take one criterion as a base for classification and sub-theories, while the human is a complex nature. The function of humans interacts and complicate. The emerging adult already as an embryo has been creating a personality that may be crucial for its future destiny. One event as first memory of a child at age 1-2-3 may become a destiny factory to the end of emerging adult personality. Then, the complex theory of humans requires very sensitive approach to what the scientists use not only as a concept but also as terminology.

It is offered below a four-age category theory of human age in 21st century. To accept the theory one should have the tradition of thinking on people not as non-invertible biological species, but a dynamic historical biocultural category that can advance as a category but also can devolve easily. Then, the classification below has the spirit of framework as behavior which helps people to advance and not just a scheme that reflect some observations from different social and cultural global contexts. The second mind constructor for a positive reflection is to look at world as cultural system in which there are many visible and invisible constructors, so we are not able to reveal the whole colorfulness of our world since the invisible aspects cannot be easily proved. For instance, nobody knows how one psychotronic terrorist (e.g. second generation PT in Bulgaria, P. Georgieva and B. Gajdarska) have been raising theory children – as psychotronic terrorists or as normal people. However, the second generation PT Maria Gyurova has been known as the umbrella of all criminal and corrupted affairs related to Bulgarian archaeology. In such case there is age egalitarism between three generation as endangered humanity – from the first generation (H. Todorova) toward second generation (her son I. Vajsov, P.In such case there is age egalitarism between three generation as endangered humanity – from the first generation (H. Todorova) toward second generation (her son I. Vajsov, P. Georgieva, B. Gajdarska and M. Gyurova) toward the third generation which is a very steady step devotion of society. By redefining human age as adult age of different categories, we have been looking at the human world with the right scientific glasses. Unfortunately, in science lab the goal of many is to replicate past works of chair-holders and not to think to help humanity. While the students in psychology have been taught that the psychological literature older than 10 years is usually out of date, many even future works become old and out of date in the process of objectivation of the projects since they have been based on old or not serious innovative general theory.

Social approach to the problem of age categories

The complex science of human requires regeneralization of the main categories which construct our understanding of people. Such understanding needs to have more social impact since at this moment as countries like Bulgaria shows – there is power in many places of the world which functions beyond the rational experience of human mind (see e.g. the introduction above). They function since the social system is multilayered and the power is embedded as layers which cannot be revealed as visibly corrupted. Typical is the case of psychotronic terrorism which has been practicing by Bulgarians who receive academic salaries and retirements and/or occupy positions which have been thought as position of social status. To exit such abnormal social system the main reason is that the political power and ideology in Bulgaria like a vacuum embraces the social and cultural cells, which are disabled for normal function. Any healthy social and cultural cell is either killed or has been disabled for growing as a cell which can impact the political power and ideology.

The Bulgarians who understands the tragedy of their destiny at a moment when the globalization warm spring wind embraces many countries in the world, do not have the leader who can make the nation again function as a leading world nation and not a poisoning arm of V. Putin and V. Bozhkov. Instead a lab of globalization, it has become a lab of deculturation and demoralization of society and individuals.

There are many classification of the aging of people. Probably for purity of research is better not to recall any, since the biggest danger of noninvertible devolution of science is the replications.

21st century allows construct a basic 4-age division of aging:

First age group is 0-19 years old. This is the age of birth and growing of the children as adults. The first change of our understanding is looking as children even in the baby-cradle as young adults. It is not an accident to see 1-2 year old children learning skill on tablets which the student studies in college for grade nowadays. For 21st century children and teens, life is seriously as for the so-called young adults and any age. Game is a way to express and develop emerging adultness. Then, this category is the category of emerging adultness.

Second age group: 20-50 years old. Today this is the category of young adults. The people experience in different ways the life in this age. In past it was the time of flourishing families. Today it is the time of flourishing individuals. Many prefer singlehood as opportunity to develop their personalities being attached to parents or other’s families. For those who have been already creating families, it is the period of development of motherhood and fatherhood as an integrated part of their complex social personalities.
Third age group: 50-79 years old. Today this is one of the most active human age categories. The people in this category reeducate themselves, build first and life-long families, enjoy to the fullness of entertainment since clearly understand that life is very short and the life is about value personality which is a value not only in working but also in entertaining context. This age understands the life in the best and in the worst way. The corrupted politicians and academicians, as well as the psychotronic gang leaders come from this age, as well as advanced art generous works, emerging artists with all potentials to become the best; while many pseudoscientists fail exactly in this age, since the quality and not power and autocracy defines the real value.

Fourth age group: 80 years and older. This is the age of limitation of the human abilities as physical appearance but still active mind which can surprise everybody. The grand-grand parents may raise the most wonderful grand-grand- children or even own children. The authors with talent may produce their most wonderful works. This can be also the age of serial killers, most aggressive sociopath who in past used the power, and who believe that power can be abused at any age. It is the final age of humans when the people are human because of humanity in them that they have developed, as wild because of the human wildness which always exists in everybody but has been enculturated and expressed in different ways by different people.

In light of above classification we have four levels of adults:
1. Emerging adults (0-19 years old)
2. Young adults (20-49 years old)
3. Advanced adults (50-79 years old)
4. Matured adults (80 and older).

As personalities these categories cross, interact, overlap, devolve and change at different scales and values. Health, moral, social and political contexts and activities impact the people from different ages, although age is a crucial leading biological and cultural factor I development of each human personality.

The complex theory of humans may help to make the life more valuable since many values today have been corrupted even by the highest paid academician, since today science is not a destiny but a profession and it has been often occupied by selected people for criminalization, demoralization and corruption of 21st century society (Bulgarian case study), which is the context of accumulation of criminal wealth – a goal of many in which wildness dominated instead the enculturated human being.

Social application

There are many social applications of the four-age category theory. In this work will apply the theory to criminal behavior. For instance, it is stated:
“… job stability and marital attachment in adulthood were significantly related to changes in adult crime -- the stronger the adult ties to work and family, the less crime and deviance among both the delinquent and control groups” (Sampson & Laub, 2004, 7).

This statement can be applied to any age from the earliest appearances of crime in childhood which is emerging adult age. The scale is different, although studying different age groups and treating all humans as different categories adults as mind (which is different not because of age only, but because of different enculturation) may help to decrease the crime, since the same conclusion would come if we compare the emerging adults behavior in different social context – crime usually characterizes the emerging adults which have broken or disabled attachment to family and job related duties (including family duties, care about personal environment, household duties, community duties at different scale).
