".......although what goes on in their heads is a different matter...."
Too true - ladies are rather more complex creatures as the following indicates only too clearly:
I used to enjoy teaching my UAS ladies, because they would never settle for being 'average', unlike the lads. Some (of either sex) couldn't make the required standard in the required time, but on the whole the ladies generally put more effort into their flying.
And at least they washed their flying suits. Unlike the lads', which frequently stank of beer, barbecue and BO!
