 You can download it at the Air University Press website. I don't make any money off the book. It is a U.S. Air Force book that I submitted to them, no copyright. And they shipped the book out. I'm sure you'll be able to provide the email address in a link to this podcast. Wonderful. And I want to thank you for taking time out of your busy day today to talk with us and to delve into some really interesting and thought-provoking concepts and ways of being. So, Ben, I also want to thank you for your dedicated service to the country.
