There is no gender difference when the product you are selling is your brain. I don't see a point in pretending there is no difference, where you primary product is your physique.

Some random quotes from the wiki article:
"Several studies have shown the hippocampi of men and women to differ anatomically, neurochemically, and also in degree of long-term potentiation."
"In accordance with the sexual dimorphism of the amygdala, the right VPMC is more dominant in an active limbic system for males while the left is more dominant in females. These differences carry out to a behavioral level."
"Positron emission tomography studies have shown that men and women ranging from the ages of 19 to 32 years old metabolize glucose at significantly different rates in the orbital prefrontal cortex. Infant males who exhibited lesions on their orbital prefrontal cortex struggled with object reversal experiments, but females exhibiting such lesions did not have impaired performance in object reversal."
Entirely? That's an incredibly strong claim. Do you have any evidence for this assertion? Is such an assertion even plausible, if you are objective about it?
