there is a saying that a man's ego is just as fragile as a woman's heart.
contrary to belief, men and women are still similar mentally despite stereotype that women are more emotional or that men are more impatient.
studies show that women are mentally more empathetic and coherent than men, and it proves as a skill ; women are often teachers, doctors/nurses. This is because both sides of the brain develop earlier as a foetus in females than males.
However, studies show it is true that males are more advanced in maths and geometry while females are more advanced in language and fine motor skills e.g. handwriting, creativity. This can be shown from an early age until puberty, when the brain changes.
Girls often change earlier than boys, when they become faster and more accurate in communication. Boys catch up, but develop other skills since men and women sometimes use different parts of the brain for the same function e.g. working out arithmetic challenges.
Men and women are both able to perform tasks, and although they are both very much equal and balanced mentally; there are women who are professors and men who are linguists- there is no determining the level of difference in each individual.
