Why big men tip more than women?

Nathan Holton, Professor UNIVERSITY of dentistry research group the same UI has conducted to measure the size of the nose of the 38 European people involved in research at the University of Iowa at the age from 3 to 20 years. Through the study, the research team discovered that the males and females have equal nose size from birth until puberty (about 11 years). From then onwards, the size of the nose becomes more different.

At the age of puberty, males grow larger women.

In terms of biology, in this age, men began to thrive on online while women developed adipose glands. A previous study also pointed out that, in the age of puberty, about 95% of the body weight in men composed of fatty substance intake compared with 85% in women.

"This issue has been given discussed in medical documentation before, but this is the first time we conduct research on the differences in the size of the nose in men and women. Research indicates that, when the body of men and women develop in adulthood, men's size is usually larger than the females, due to the difference in energy demand as the amount of oxygen absorbed, basic metabolic rate and daily energy needs in the development process " He said Holton.=
