I'm due for my next hiney-scoping next year, 10 years after the first revealed a very nondescript state of meaty plumbing. By contrast, my wife is now referred to as "Punctuation", as she now has a "semi-colon" due to discovery of nasty polyps (fortunately, she was born with extra bonus colon length, and everything is reconnected OK).
The top end of the tract, though, gets regular peeks every 3 years, as in the past I ignored my recurring heartburn long enough to develop Barrett's Esophagus, where the esophageal cells mutated due to bathing regularly in stomach acid, and can become cancerous. And esophageal cancer typically doesn't give enough time between detection and decease to even start liquidating a decent parts collection.
