What should I do or have to be sexy?

What should I do or have to be sexy? Of money, a very muscular body, a much younger woman? Researchers at the University of Stirling in Scotland looked at the issue. For their study, they were among the three pictures used to face: that of a European, a member of the ethnic Hazda (Tanzania), and finally that of a macaque! According to you who is most likely to be the sexiest?

Scientists are not rational in this way, they have used these three portraits for any other comparison: symmetry. This may sound bizarre, but in fact these three faces have been analyzed by computer to obtain varied more or less symmetrical. It appears that the distance between the eyes or cheeks is very important. This conclusion was made after submitting several groups of people to the vision of multiple images. The opinion is unanimous: the faces elected the most sexy were those with the greatest symmetry.

For researchers, this reflects the survival of species. We would all be attracted to symmetrical faces because they reflect a notion of perfection, a greater ability to reproduce and better resistance to the vagaries of life. Why? Because the same gene codifies both the perfect balance of traits and the reproductive and immune system. George Clooney, Kate Moss, Angelina Jolie are sexy and most biologically perfect, not to mention their ability to never catch colds.
