“My adrenal gland gave me a shot of adrenaline, too. I turned purple as my blood pressure skyrocketed. The adrenaline made my heart go like a burglar alarm. It also stood my hair on end. It also caused coagulants to pour into my bloodstream, so, in case I was wounded, my vital juices wouldn’t drain away. Everything my body had done so far fell within normal operating procedures for a human machine. But my body took one defensive measure which I am told was without precedent in medical history. It may have happened because some wire short-circuited or some gasket blew. At any rate, I also retracted my testicles into my abdominal cavity, pulled them into my fuselage like the landing gear of an airplane. And now they tell me that only surgery will bring them down again.”
