Sexual education of schoolboys should begin for some years earlier as now teenagers reach sexual maturity considerably before the coevals living 100 years back, the British scientists which clause is published in Journal of Epidemiology and Community Health believe.

Absence of a due level of knowledge of intimate life among the young people which have reached physiological maturity, inevitably results in growth of number of the venereal diseases unplanned pregnancy, abusing alcohol and drugs, and also displays of teenage aggression, researchers warn.

Now, according to scientists, middle age of puberty among the British teenagers makes 12 years, and break between sexual and social development among them is now great as never.

According to one of authors of the publication of doctor Mark Bellisa, the accelerated puberty of modern children partly speaks the improved feed and sharp decrease of prevalence of some children's infections.

At the same time not less important can appear and the role of some social factors or family circumstances, marks Bellisa. Despite lacking reliable proofs of that children in socially unsuccessful areas develop faster, than their more provided coevals, in these areas such problems as high interest of incomplete families and high birth rate most sharply cost. Doctor Bellis also has specified results of recently published research according to which puberty comes much faster at the girls growing in families where there is no father.

" We can not concern to children XXI of century precisely the same as we concerned to their coevals of 100 years back as they are unlike the predecessors and are on completely other stage of intellectual development ", - has emphasized the scientist.

The professor of sexology Werner Habergeon from Hamburg has lead interesting research. He has tried to find out, how sexual life of the woman depends on color of her hair.

Also what was found out? Blondes, despite of the appeal advertised in jokes, appeared almost on last place: «Sexual life of red-haired women is clearly more active, than women with other color of hair. Red had a lot of partners and blondes, brunettes and broun haired girls made love much more often, than red-haired ladies have confirmed the fiery reputation ".

Habergeon has added, that those women, that color hair in red color, signal that they search for the partner: " Even those women, that for a long time are in stable relations indirectly speak partners that they do not feel like happy if color hair in red color. They simply shout that search for someone the best ".

Psychologist Christinas Baumanns speaks, that red-haired, actually, nothing differ from other women, except that: " Red color is responsible for passion and when the man sees red-haired lady, he thinks, that communicates with the woman who will not beat around the bush, and at once will proceed to sexual relationship ".

If the love is blind, the humor helps to open eyes.

To such conclusion there came authors of two recent scientific researches who confirm a known stereotype: women love witty men, and men love women who laugh at their jokes, informs DELFI.

That fact, that people with sense of humor are attractive, it seems obvious. Already some scientific researches for acknowledgement or a refutation of this idea however were carried out.

Eric Bressler from Westfield the state college in Massachusetts and his( colleague Sigal Belshajn from University Makmastera in Hamilton, Ontario, have constructed the research as follows. They have asked 200 students of college man's and a female to look at photos of persons of an opposite floor. Under some of them there were amusing signatures, for example: "At our school was so nasty, that at us the regular inspector" was. Under others were neutral: "I preferred to go to school on foot instead of to go by the bus ".

Women have estimated the men who have shown sense of humor as more probable potential partners, researchers and also as more friendly have found out, interesting and popular. On the other hand, the opinion of men on women did not depend in any way on their wit.

Bressler has assumed, as men and women actually equally appreciate sense of humor in the partner, but they require in a little bit (different things: women appreciate skill to make laugh, and men - ability to understand a joke.
At second investigation phase Bressler with colleagues two person of an opposite floor has asked to imagine about 130 students. One of these imagined characters herself was joker, and the second - appreciated another's humor. Then them have asked, whom they would choose from these two for close relations.

Women, as a rule, preferred men - merry fellows, and men - women to whom they seem witty.

Bressler considers, that his supervision can help to understand, how at people during evolution the sense of humor in general was developed.

According to the theory offered by psychologist Dzheffri Millerom from University of New Mexico, the woman prefer witty men as presence of humor proves, that at them an active and healthy brain and consequently - a good set of genes. " It Is rather effective and reliable way to be convinced available creative imagination and intelligence ", - speaks miller.

If this theory is true, the woman, choosing itself in partners joker, has more chances to get healthy posterity to which these genes are transferred. Thus, there is a selection favorable for men with humor and women which appreciate this humor.

What all this means for people which search for the love? Being the scientist, instead of the expert in the field of relations, Bressler is at a loss to give the answer. However eventually surrenders and gives women simple advice: "If the guy of you does not interest, it is not necessary to laugh at his jokes ".
