Men and women are very different, arise is because many such as "women are from Mars and men from Venus". Not only physical differences because they also involve different. The women are more emotional and tearful however men are more stronger and have little sensitiveness.
Sometimes speaks of the war of the sexes, the gender differences because falling in machismo and feminism and stereotypes. There are clear visible differences, for example, men are quick to buy clothes, women outnumber the men who do housework, men tend to look at the attractive woman's physical, women are more sensitive and not often as dirty much as men. But today there are fewer and fewer differences are less, men look better even some makeup, and some women are doing jobs that were previously only for men for example mechanics.
For me women and men must be different, for complement, perform the same tasks, it would be very boring a world where we all acted the same, in which all men acted as a mom, it would be crazy. I really could not develop well as people. Leaving aside the differences between women and men, we must recognize that they cannot live without eacht other.
