Very good John! Not many people see that at the bottom. Just curious, did you know what horology was? Not many people do, I usually don't even bring it up. As a man of science and nature, I have always been interested in mechanical time keeping. I think my interest in science and mechanical time keeping started when I insisted on wearing a watch when I was six. Not any watch, but a watch with a chronometer, so I could take it apart and see how it worked. This is so cool! people are learning about periodic elements and horology. Now everyone who reads this will have even more useless knowledge. Oh, this couch is comfy.
