Nobody ever sees the inside of their body, ... It's wild ... it's not nearly as orderly as you think it's going to be.

I'm drawn to the taboos that surround the human body. I find it fascinating that we are repelled by many of the acts and processes that keep us alive.

People are surprisingly off put just by saliva, the substance that you carry around in your mouth. You swallow it. You have no objection to it. But then it leaves your body, and you're just revolted. So it - that - just that right there to me is a fascinating thing.

To keep your he-man jaw muscles from smashing your precious teeth, the only set you have, the body evolved an automated braking system faster and more sophisticated than anything on a Lexus. The jaw knows its own strength. The faster and more recklessly you close your mouth, the less force the muscles are willing to apply.

You won't see me writing about particle physics, or even planetary geology, or chemistry. I practically failed chemistry, and if I had to write a book in any of those areas, I don't think it would go well.
