I have been a science reporter for twenty-eight years, my entire working life, and for most of that time I had little interest in writing a nonfiction book for adults. It was too close to my day job. When you spend eight or nine hours a day sorting through studies, interviewing scientists, chasing down contrary evidence and arguments, you want to shut down the factory at the end of the day. You don’t want to do more of the same; you don’t want to do more at all.
