* Cool hands of women
A study conducted by the University of Cambridge, Britain, that the proliferation of muscles in the hands of men generates more heat, while preventing the fat in the hands of women to leak the warmth to their hands at the same speed.
* Men's noses are bigger
Even if men and women are the same size, men's noses are 10 percent larger than the noses of women, according to a study by researcher Nathan Holton at the University of Iowa in 2013, where 20 men and 18 women aged 3 to 20 .
At the age of puberty, Holton found that men's skulls were larger and their noses. "In adulthood, the muscles in the boys' bodies grow, and the growth of these muscles needs more energy and more oxygen, , While fat grows in the bodies of girls, and do not need fat to oxygen, the size of the nose than men.

Men have a type of color blindness that results from the presence of a genetic component in the brain that is rarely found in women.
* Men are more able to observe movement
The University of New York City study also found that men's eyes are more able to observe movement than women's eyes. This is due to the increase of optic nerve cells in the man's brain than in the woman's brain. Others, where part of his brain is occupied with the movement, is less focused during the dialogue.
