A reader: “Per your Corner comment, I suspect you are having a

colonoscopy. I am an old veteran (Crohn’s disease, have a scope every

2-3 years) and I would urge a person who reveres science as you do to

forgo the sedation and do it awake and alert – they now use a fiberoptic

video camera and it is fascinating to see the inside of your colon. It’s

really not that uncomfortable – like bad gas now and then, but hardly

excruciating.”

Er, yes, I sure do revere science, but my reverence has limits. I have

seen the inside of other people’s colons (though not Katie’s) on TV

science shows. Isn’t it a case of seen one, seen ‘em all? Are the

follicles of Lieberkuehn going to look strikingly different in my case?

Let us hope not.
