I had a sigmoidoscopy in January 2000, and there is no way I would ever allow myself to go through such a procedure again. I was told beforehand that it would not be painful and would only be minimally uncomfortable. However, while I was lying on the gurney with a flexible endoscope up my rectum, I knew right then and there that if the medical staff were KGB agents and I were a spy with top-secret information they wanted, I would have given it up immediately if I didn’t have a poison capsule to bite down on and end my life. Anyway, I came across this video today and found it interesting.
