Your digestive system is your body's Fun House, whereby food goes on a long,
dark, scary ride, taking all kinds of unexpected twists and turns, being
attacked by vicious secretions along the way, and not knowing until the last
minute whether it will be turned into a useful body part or ejected into the
Dark Hole by Mister Sphincter. We Americans live in a nation where the
medical-care system is second to none in the world, unless you count maybe
25 or 30 little scuzzball countries like Scotland that we could vaporize in
seconds if we felt like it.
