Jeffrey Wertz was born in Altoona, Pennsylvania, but since his father was a soldier in the U.S. Army, he spent much of his childhood living on various Army bases across the U.S. and Germany. He graduated from the University of Maryland with a degree in business while serving in the military in Frankfurt, Germany. After serving eight years in the military, Jeff took a job with the Department of Defense, and has spent most of his career working in Germany, Italy, Japan, and Korea. The subject of this book is his passion. While living and traveling in different countries, he has spent years observing the actions of men toward women, and discussing cultural differences and the interaction between couples with men and women from these countries.
