Randy Thornhill, an evolutionary biologist at the University of New Mexico, has been engaged in symmetry research for the past 15 years. He used a scanner to input the faces and bodies of different people into a computer to determine symmetry ratios. The survey results show that both men and women believe that the opposite sex with good body symmetry is more attractive. Thornhill explained that this is a genetic advantage that indicates a person has good survival ability and that she/he is very healthy. In comparison, men view women in a slightly different way. They pay more attention to the symmetry of a woman's face than her body.

Women with short chins and men with thick eyebrows are most popular. Thornhill said men and women with these characteristics are more attractive because they predict reproductive health. Estrogen limits the growth of bones in a woman's lower face and chin, making them relatively short, and it also controls the growth of women's eyebrows, making them more prominent. Men are affected by testosterone, which contributes to a good lower face, chin, and thick eyebrows.

Devendra Singh, a psychologist at the University of Texas in the United States, studied the ratio of waist to hip circumference and found that the ratio of waist to hip circumference is 0.7 (indicating that the waist is much thinner than the hips) Women are the most attractive to men. Scientists once analyzed the body shapes of Playboy magazine models and Miss America contestants and found that most of these women had a waist-to-hip ratio of less than 0.7. For women, men with a waist-to-hip ratio between 0.8 and 1.0 are most attractive. At the same time, men's broad shoulders are more arousing to women's sexual desire. Research also shows that people who are within the ideal waist-to-hip ratio range, regardless of their weight, are less susceptible to cardiovascular, cancer, diabetes and other diseases. And women who fall within this range also experience fewer difficulties getting pregnant.

Study by German scientist Manfred Milinski and others found that when people choose a partner, they instinctively use their noses to judge whether the partner is suitable for them based on their smell. Scientists explained that this function of relying on the sense of smell to assist in identifying your sweetheart is related to the body's immune tissue. When people are close to each other, the odor emitted by their bodies will be sensed by each other and judge whether it will cause discomfort to the tissues and organs in the body. Generally speaking, this kind of identification of the other person's body odor will not be affected by external smells. That is to say, although the appropriate use of perfume may help to enhance the other person's goodwill, it will not play a decisive role. A study from the University of Chicago also showed that women prefer men who have a similar body odor to their fathers.

Perfect breasts will attract men’s attention, and the most perfect breast curve, viewed from the front, presents an “equilateral triangle”, which is commonly known as the “golden triangle point”. These three The points are the depression in the middle of the clavicle and the two nipples. If the straight line connecting these three points is an equidistant equilateral triangle, it will meet the perfect proportion of the "golden triangle point".

It is not easy to cultivate into a woman who is loved by everyone. Most of the things mentioned above are innate. If you want to cultivate in the later stage, you must have a certain amount of perseverance. Only by exercising your imperfections can you get ahead.
