Do you just mean on a physical level?

Yes.Feminenity and masculinaty,and that basically it.For me,I was born a female,so I identafy as a female,and I'm attracted to guys,but I'm sort of boyish as well personality wise,so it's really weird for me.*+++++*

Yes, the many other biological differences. Our hormones make us act very differently, our brains think differently, our bodies and their capabilities make us different as well.

Yes. Our brain patterns are different, our chemical build is different, we have different hormones and different cromosones. We are different all the way down to the cell.

One word - hormones!

Woman are emotionally stronger than men+5

Besides all the physical differences- I would have to say that men and women are on the opposite ends of the "Emotional" spectrum. Women are all about their feelings, and men are all about their egos- no offense to men or anything, that's just what I've observed. +++

The only thing that the imbecile who wrote that book got right was the first book Men are from Mars and Women are from Venus. Pretty isightful, and he should have stopped there.

There are plenty of people who think the only differences are caused by socialization, but then they have to answer this question: If your theory is true, then why is Homo Sapiens the only species on earth in which the sexes are basically the same? 20-some years ago a doctor botched a circumcision and got the kid's parents to agree to a sex-change operation to conceal what he had ruined. They did and named and raised the child as a girl. He was miserably unhappy, did boy things like standing up to relieve himself, and after he found out and stopped taking the female hormones, had only a few short years of life as a male before committing suicide. So much for liberal social-engineering theories.

Men are, generally, physically stronger.

Apparently

Like Jack Lemon puts it, "It's like a whole other sex!" Women are completely different! Starting with the brain, a woman's brain is wired differently and operates differently. "Women on the other hand have four times as many brain cells (neurons) connecting the right and left side of their brain. This latter finding provides physical evidence that supports the observation that men rely easily and more heavily on their left brain to solve one problem one step at a time. Women have more efficient access to both sides of their brain and therefore greater use of their right brain. Women can focus on more than one problem at one time and frequently prefer to solve problems through multiple activities at a time. Nearly every parent has observed how young girls find the conversations of young boys "boring". Young boys express confusion and would rather play sports than participate actively in a conversation between 5 girls who are discussing as many as three subjects at once!" Source: http://www.oregoncounseling.org/ArticlesPapers/Documents/DifferencesMenWomen.htm The female brain has more of it's functions dispersed throughout the brain, rather than localized, as in the male brain. Women have the ability to see more colors than men. Women communicate in more complex patterns. A woman's pelvis widens to make child rearing possible. Women undergo hormonal changes that men do not. Women are genetically different in their sex genes. Yes, there is a real difference between the sexes.

Oh, yes, nutmeg. How old are you, anyway?

Have to ask.....what planet are you from????

I think both are made different physically. Emotionally there might be some differences based on what they have to achieve int his world. Like women have to become moms, which may need a bit more emotional than being a dad I guess.
