One of the joys of turning 50 is adding one more thing to the doctor's recommended test slate: the dreaded but very important colonoscopy. A big enough deal that its counts as a new thing, but really wasn't as bad as I had feared. A few days of preparation, a lot of anticipation, and a short procedure under anesthesia.
I don't remember a thing, and didn't even wake up to a room full of space aliens in a UFO.
But the best news is that I had normal results, no need to repeat this for another 10 years, and this new thing is done.
