In plain simple word, men and women are different naturally, biologically. Their brain functions differentky, rather men and women use their brain differently .

Men are intrigued by numbers and details and women by people. Men have better road sense than women who are always bothered about finding their way back.

In relationships, men are insensitive and unable to read facials expressions. Women pick up subtle tones of voice and facial expressions fast .women excel at language, like finding the right word when required.

The right side of the brain is the seat of emotion and left of the reason and women’s command over language is explained thus, they draw feelings from the right brain and reason from the left brain, when they use word.

About reading faces .a happy face can be spotted far easily than a ad one .Men find it troublesome to read emotions on the face, especially sadness.

Research reveals that women are twice as likely as men to suffer major depression On why women are less able to separate emotions from reason.Neuroscintist feel that there is non stop chit chat between left brain and right brain in women and hence the confusion .

In male brain the left side barely knows what the right side is doing .Because the bundle of nerves which forms a communication link between the two brain sides is smaller in men and larger in women.

Women have better intuition too, this again because of the above reason .The combination of left brain’s rationality and right brain’s emotion

Women despite having smaller brain than men have more neuron.

Only one factor is known to effect the nerve cell, that is sex –hormone .Girls with abnormally high levels of male sex hormone are likely to prefer cars and trucks and other boyish toys whereas boys insensitive to male sex hormone are likely to be better at language.

Research shows that foetus develops 50 trillion nerve cells which become functional only when they respond to external stimuli. During the first year of life, the most frequently stimulated neurons form the information processing network for future whereas the rest wither and die. So in a way experience determines the structure of brain or vice a versa. This means that brain is malleable, that it can be molded. In people whose hands were amputated the part of brain that once registered feelings from hands vanished. Which means a part which isn’t functional just vanishes.

Social interactions can sculpt the developing brain. So it is nature both that decide the way we think .

But until science throws more light, however clichéd- the phrase ‘Men are from Mars ,Women from Venus’ will remain true .
