Acknowledgments

I want to thank my wife, Christie, who always supports me during the many hours I spend in research and writing. Christie—I couldn’t do it without you!

I also want to express my thanks to my editor, Jamie Chavez, who had the difficult task of slogging through the rough draft and helping me break down a lot of scientific facts into bite-size, understandable, and actionable bits. Jamie—thanks for your help. I needed it.
