Did you know that women’s brains are smaller than men’s? The average women’s bra

Did you know that women’s brains are smaller thanmen’s?  The average women’sbrain weighs 10% less than men’s．Since research has shown that the bigger the brain, the cleverer theanimal, men must be more intelligent than women．Right?Wrong．Men and women always score similarly onintelligence tests, despite the difference in brain size．Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just thesize of the brain．The brain consists of “grey matter” and “whitematter”．While men have more of the latter, the amountof “thinking” brain is almostexactly the same in both sexes．

It has been suggested thatsmaller brain appears to work faster, perhaps because the two sides of thebrain are better connected in women．This means that little girls tend to learn tospeak earlier, and that women can understand sorts of information fromdifferent sources at the same time．When it comes totalking to the boss on the phone, cooking dinner and keeping an eye on the babyall at the same time, it’s women who come out on topevery time．

There are other importantdifferences between two sexes．As white matter is the key to spatial tasks, men know better wherethings are in relation to other things．“A greatfootballer always knows where he is in relation to the other players, and heknows where to go,” says one researcher．That may explain one of life’s greatmysteries: why men refuse to ask for direction and women often need to!

The differences begin whenfetuses（胎儿）areabout nine weeks old, which can be seen in the action of children as young asone．A boy would try to climb a barrier before him orpush it down while a girl would attract help from others．These brain differences also explain the fact that more men take upjobs that require good spatial skills, while more women speech skills．It may all go back to our ancestors, among whom women needed speechskills to take care of their babies and men needed spatial skills to hunt,according to one research．

If all this disappoints you, itshouldn’t．“The brain changes throughout our lives according to what we do withit．”says a biologist．
