Good god. I went to get one, and in the pre-screening, the anesthesiologist asked if I wanted to be awake for it. “Doc, I don’t want to be awake, I don’t want to feel a thing, and I don’t want to remember a thing. Put me out.”

Requiring people to be awake is a good way to guarantee they don’t get the procedure. Which mathematically makes it far more likely for the insurer to incur enormous colon cancer treatment expenses, erasing their profiteering.
