24 hours of bladders

I stayed up for 24 hours straight yesterday helping a friend edit a video for a medical conference. I spent twelve of those hours staring at footage of kidney stones floating in pee, enormous, red prostate glands, and the wall of some guy's bladder. All I can see is yellow. I would post some screenshots, but I'll spare you. Pray you never have a problem with your urologic tract - the camera they use to take the shots is about the diameter of a pencil.
