Frigaj ga, ja upravo čitam knjigu koja, ako dobro shvaćam, tvrdi da se uopće ne razlikuju, osim u težini (koja nije vezana ni sa čime posebno), ko što je valjda srce žensko manje od srca muškog, ili je bubreg muški manji od ženskog, pa ne postoje studije, lupam "muških bubrega" versus "ženskih bubrega":

"In Delusions of Gender Cordelia Fine does a magnificent job debunking the so-called science, and especially the brain science, of gender. If you thought there were some inescapable facts about women's minds - some hard wiring that explains poor science and maths performance, or the ability to remember to buy the milk and arrange the holidays - you can put these on the rubbish heap. Instead, Fine shows that there are almost no areas of performance that are not touched by cultural stereotypes. This scholarly book will make you itch to press the delete button on so much nonsense, while being pure fun to read."
