How the Human Body Works: Big Questions Answered

You live inside this body every single day, and you still have no idea why you yawn in a boring meeting, why your skin turns purple after you bump a table, or why the hair at your temples went grey first. The questions are simple. Nobody ever answered them.

This is a big-questions tour of the body you already own, told in short chapters you can finish on a commute. Each one takes a single irresistible question and answers it properly, cashing out the numbers in analogies you can actually picture, from blood vessels long enough to circle the planet to the hundred trillion cells currently working on your behalf. Plain language, real science, and one genuine wow moment every time.

By the end, the machine you walk around in stops being a mystery and starts being the most interesting engineering you have ever heard about. Press play on the drive, at the gym, or over the dishes, and start understanding yourself from the inside out.
