“But some individual parts of the female brain are denser…. [Oops did they really say denser? Surely they refer to the number of cells per mass unit rather than “dense” in the sense of unteachable or stubborn? :-)”
Women can be very unteachable. Has a man ever been successful in teaching his wife how to make a sammich or cook breakfast more efficiently?
It can’t be done.
Men can be very unteachable too - because they think they already know everything. Hee-hee!
Although there are always rare exceptions to any blanket statement, after trying to teach my wife to back the boat trailer up I completely agree that there are just somethings that can’t be taught to an XX chromosome.
