I have a grid of ribs, but I have no spine. I breathe in the heat, but the chill is mine. I am always boiling under the hood, Keeping things cool like a good guard should. If I spring a leak, you’ll be stuck in the smoke, Because when I stop working, your engine’s a joke.

Often unreliable, depending on who you ask. Alzheimer's robs this from us, what a pain in the ass..

I was an ancient healer; to be honest, I wrote the book. Modern doctors still recite my name -- some even call me daddy. I'm oft confused with people who say one thing and do the opposite. I begin as a hungry, hungry mammal; let's use the nickname to start. And I finish as containers and boxes for things that are heavy and large. I am a person from history. What is my name?

Amazon, Phoenix, Mississippi, Colorado. Rollin', rollin', rollin' ...

I extend an hand and have your back, if you’re feeling squishy or a spine you lack. And although I’m something you like to hide, the funny part of me can split your sides.
