OK. You turned 50. You know you’re supposed to get a colonoscopy. But you haven’t. Here are your reasons:

1. You’ve been busy.

2. You don’t have a history of cancer in your family.

3. You haven’t noticed any problems.

4. You don’t want a doctor to stick a tube 17,000 feet up your butt.

Let’s examine these reasons one at a time. No, wait, let’s not. Because you and I both know that the only real reason is No. 4. This is natural. The idea of having another human, even a medical human, becoming deeply involved in what is technically known as your ”behindular zone” gives you the creeping willies.

I know this because I am like you, except worse. I yield to nobody in the field of being a pathetic weenie medical coward. I become faint and nauseous during even very minor medical procedures, such as making an appointment by phone. It’s much worse when I come into physical contact with the medical profession. More than one doctor’s office has a dent in the floor caused by my forehead striking it seconds after I got a shot.
