My left kidney is 1cm longer than the right one

And I only know that because I had an abdominal ultrasound today, which measured on the medical procedure scale of 1 to medieval is a .5, because while it is somewhat poky and goopy, was actually fun and educational. I got to see all my organs and several blood vessels (actively pumping!), which was really fun, and I got to give out business cards to the technicians. It almost makes up for eating a fat-free dinner last night, which was seriously traumatic.
