The best parts of Conley 's book are about deep , institutional resistance to the way that otherwise admirable male professors understandably draw on their training of 20 years ago , which assumed the 70 kilogram male body as the human norm and left them totally ignorant of female health problems ; the way training in elite specialties like neurosurgery still promotes a specific kind of cowboy bravado , which encourages women to bail out for gynecology .
Cronley 's books are about resistance to gender norms .
