That should be the favorite song of any installer who tries to fight this one. Mother Nature is stubborn when it comes to evening out things. She is forever trying to put everything on our planet back into the elemental state from whence it came. Mix iron with carbon and you get steel. We like that. It’s useful. But Mother Nature looks at the steel, shrugs and turns it to elemental rust. There’s a fancy word for that — entropy. I feel it in my old bones most mornings.
Sit next to a radiator on a cold day and you’ll feel The Second Law of Thermodynamics. The radiator is hotter than you are, so energy flows from it into you. Nice. The opposite happens when you’re on the ice rink. Unless you happen to be dead, you will be warmer than that which is beneath your skates, so get skating because if you stand still too long, the Btu in your body will dive into that ice and make you miserable. Brrr!
