I've never had a colonoscopy in my life. However, now that I'm in my sixties, my medical practitioner is making meaningful noises at me that it's long past time I did. I keep protesting that everything feels fine, but my quibbles are falling on deaf ears.
That being the case, I thought I'd try to prepare myself by learning from the experience of others. This guy isn't helping.
