I
called my friend Andy Sable, a gastroenterologist, to make an
appointment for a colonoscopy. A few days later, in his office, Andy
showed me a color diagram of the colon, a lengthy organ that appears to
go all over the place, at one point passing briefly throughMinneapolis .
Then Andy explained the colonoscopy procedure to me in a thorough,
reassuring and patient manner. I nodded thoughtfully, but I didn't
really hear anything he said, because my brain was shrieking, quote,
'HE'S GOING TO STICK A TUBE 17,000 FEET UP YOUR BEHIND!'
