Physical beauty is something connected to your genes. Researches linked it to body shape, facial proportions and symmetry.
Estrogen (female sex hormone) load has been linked to feminine face and body ratios. Women with waist-to-hip ratio (WHR) around 0.7 (0.67-1.18) are most desirable to men, while a 0.8 to 1.0 WHR in men is attractive to women. Fat storing in
the body is under sex hormones' control and the proper levels of estrogen in women and men will produce the right WHR ratio. Those having the right WHR, no matter their weight, have been found by many researches to be less vulnerable to conditions like cardiovascular disorders, cancer and diabetes and are more fertile.

The symmetry is another issue. Even at the stage of fecundated egg, the human body starts developing from dividing cells. If each division went perfectly, we all would be perfectly symmetrical, the left and right sides being mirror images, a condition called homeostasis. But there are always environmental disturbances, as the organism does not live in a constant environment (food, temperature, humidity, predators and so on) and this slightly alters the division.

This explains why any human or animal presents a certain degree of asymmetry between the right and the left side. Smaller symmetry means an individual has powerful genes enabling him to stand bad conditions and survive better, being more healthy and fertile and research shows that the more symmetrical you are, the more attractive and healthier potential partners you'll find. Your genes will deliver the offspring a better chance to symmetry and cope with perturbations.

All these differences are normally low, just a few percent (visible asymmetry is caused by disease) but the brain perceives this, even if not consciously. Men with higher symmetry also have been found to have more sexual partners (women are more choosy, they just have more competitors). In women, studies found that the higher the breasts' asymmetry, the higher the risk of experiencing breast cancer.

But a new research made at Brandeis University challenges all these. The study says that a pretty face is not an indicator of health. In men, the correlation was absent and in women it was actually the opposite.

The researches believe that the negative correlation in women could be linked to the fact that attractive women have a more active social life that exposes them to more germs, but this is just a theory. A more reliable sign of health in women appeared to be the amount of smiling rather than beauty, while increased testosterone amounts in men just caused a harsher face, further away from the classical beauty standards. And a man's smile was not a health clue at all.

"Perhaps in our distant past, attractiveness was strongly linked to health. In more modern times this relationship has been weakened, but our responses have yet to change." said co-author Victor Luevano of Brandeis.
