More Bang for Your Butt?

I got my fifty-year-old physical this week and the doctor was really pushing the colonoscopy-- I asked him about pooping in a box but he said that's not as reliable and you have to do it every year-- while a colonoscopy is good for ten years and because of the prep, it is a "complete reset for your colon"-- yuck-- and then he drew some pictures that made me dizzy and said that of any procedure, the colonoscopy is "the most bang for your buck" and then-- and he was trying to be optimistic, but I found it disturbing-- he said, "we like to start them now at 45, so you get one at 45, 55, 65, 75 . . . and then you're done" . . . so four colonoscopies and then you get to die!
