According to foreign media reports, a new study shows that long-distance runners more attractive, sexier, because of their higher testosterone levels. In fact, in everyday life, people often do not consciously being attracted to a certain person, which in addition to the testosterone level factors, there are many other factors or evolutionary biology field. About charismatic, sexy and attractive degree of scientific secrets, scientists may be able to uncover the latest research results of some of the answers.
1. facial symmetry
Darwin once said, "In men, there is no common standard on whether the body beautiful." However, the latest research shows that there are some common views on the beautiful, and not only applicable to all cultures, and even in the whole animal kingdom also suitable. Perhaps the most important thing on the face symmetry. Has a left and right symmetrical face, in fact, a perfect biological advertising, it seems to tell all possible objects, in this body good genes there. Symmetry is not generally considered to be the presence of development had problems, such as health problems, genetic problems, alcohol poisoning in the womb.
In addition, facial symmetry is also usually there are some contact and goodness, extroversion, responsibility, therefore better surface usually easier to make friends, find a job more easily. That is why many people choose plastic surgery through the nose, straightening teeth. However, from a biological point of view, they are deceiving their partner, because no matter how beautiful they now look appearance, but they actually inherited genes may still be problematic.
The symmetry is important not just exist in the facial features. Related research also showed that men with possession of body symmetry combined women are more likely to achieve orgasm. Similarly, those breasts shapely women's reproductive ability. Symmetry of meaning even in the animal world is also reflected. Yan female who prefers symmetrical male Yan tail, they see this as a growth has a high genetic quality and stability of the mark.
2. finger length
Women blind date, you may wish to look at each other's hands. Studies have shown that men's hands can reveal many secrets. In recent years, scientists have found that the presence of finger length and testosterone levels in men some interesting connections, and this feature before their unborn in the mother's womb had been revealed.
Compared with the index finger, ring finger longer, higher testosterone levels. This is important. Because higher testosterone levels, which means the more sperm count, fertility stronger, better cardiovascular health, better genes. In addition, the longer the ring finger, may face more symmetrical, but also more attractive. However, for those who wish to find a woman has a long ring finger of her boyfriend, the need to remind one thing, this boyfriend might also prefer philandering. On the contrary, those from finger length is generally male, you may find a more long-term, more stable and loyal companion.
3. Hair
It is also used to make Darwin puzzled. Darwin had tried to find out why men prefer blond blue eyes female reasons. However, he eventually gave up, because he discovered that in fact not everyone has such a preference.
Caucasian blonde blue eyes of the physical characteristics is considered to be about 1.1 million years since the proceeds of the Nordic tribes. These tribesmen with ice receded and constantly open up to the north. For them, the blonde might have more use evolution and survival. Reduce skin pigmentation makes it easier for the ultraviolet into the body, and UV is a necessary condition for synthesis of vitamins. Therefore, the blond blue eyes of women may be more healthy and live longer.
However, some archaeologists believe that there was more than a period of war, many men were killed, and therefore harder to female mate choice, more competitive. Paleolithic hunters most like the blond, and they tend to be able to beat the competition and therefore may be more healthy. Some blond blue eyes female hair color will darken with age increases, so the young blonde is also considered a symbol of sexuality stronger.
Interestingly, women usually Caucasian blonde blue eyes estrogen levels than those with dark-skinned people is much higher, but also may be manifested in a good facial features, such as a smaller nose, chin more pointed, narrower shoulders the skin is more tender, less body hair and so on. However, a recent research has revealed the world's most beautiful women turned out to be a brunette female. In 2011, the "Scandinavian Journal of Psychology Scandinavian" a research paper also believes brunette woman more attractive.
4. Shape
As the length of the finger has a perfect proportion, like, people can quickly calculate the future in some way shape data lover. Of course, can be calculated based on the genetic aspects of the trail, we usually first think of bone ratio.
Men prefer the waist-hip ratio is 7:10. Female hip and breast size is the characterization of fertility, so there is an evolutionary relationship between the two. In addition, body mass index (BMI). After measuring, the female body mass index is at 20.85, with such weight women are the most attractive. Scarlett - Johnson was picked to have the most beautiful body of a woman.
Female spouse usually when body is required, but there is no specific criteria. For example, some spouses waist-hip ratio is 9:10. The most perfect male body shape, body fat should be about 12%, which is also an important indicator of the body's immune system can work properly.
In addition, the limbal ring is also considered a symbol of the young and healthy. A study in 2011 considered, with dark limbal ring of men and women more attractive.
5. odor
Animals in the pursuit of a partner, will secrete some chemicals, the equivalent of courtship signals. Whether humans secrete pheromones, scientists from different perspectives. However, we can be detected by smell and the presence or absence of genetic coordination between spouses. The study found that we can sniff out the match by our immune system, other genes can compensate for their lack of genes, so the two sides can give birth to healthier babies. In fact, most coordinating partner in the gene that should be with their most different people. Smell of sweat-stained T-shirts men, women prefer those testosterone levels higher odor, especially when they are in the best child-bearing age.
However, scientists at Newcastle University in England found that oral contraceptives may prevent women's access to these important genetic clues, because the drug has changed the hormonal information. When women take birth control pills, also it means that they are more willing to stay with close family members, it is often only attract people with their genetically similar. For people who want to find the object, that hope may be slimmer.
6. balance
New research shows that, in order to get people's attention in a blind date activities, appearance, we should look to coordinate the various parts, proportioned. Has a "balanced" appearance of the people, the equivalent of a set of genes play ads, tell someone you have a good reproductive capacity. The study found that the most perfect case, the distance between the eyes and mouth for 36% of the length of the face, the face and eyes should be wide IPD 46%.
7. Sound and mouth
Men are more willing to choose high-pitched female, because it represents the young. As women age, the tone will become low. High tone is also considered petite. Women listeners like to listen to the bass, because it means that the other side was a huge man.
Men are more likely to attract women loved to laugh, of course, in turn, is not the same. The study found that women love to laugh more attractive, while men laughing and joking, the debased.
