Surrendering All One's Secrets To The
Magnetic Resonance Imaging Machine
'A woman in an MRI tube has few secrets. The man at the control console knows the size of her heart and the contents of her womb. He knows if she's had her breasts enlarged or her stomach stapled. He can see into her bladder and knows whether she's wishing she'd stopped by the restroom before climbing onto the exam table.'
--from Bonk--the Curious Coupling of Science and Sex. We've only grazed through the book, but found this passage to be especially compelling.
