Let's begin with a confession: this book was written by a living organism about other living organisms, using a brain that's technically still arguing with its own gut bacteria.
Biology is the study of life - that strange state of matter between mineral and mess. It's the universe's most ambitious chemistry project, conducted under the slogan: "What happens if atoms start caring about things?" Life is improbable, chaotic, and weirdly clingy. It self-replicates, self-repairs, self-destructs, and occasionally writes self-help books. It takes in energy, rearranges molecules, and insists it's important - all while slowly decomposing. And somehow, it works.
