When he published this book, Eric Amstutz was about to turn 40 years old and often heard that he looked at least a decade younger. He didn't come from a long line of models, tan Greek Gods, or movie stars. He's an average, middle class, pasty white guy who, despite serving in the harsh environments of the US military for nearly 20 years, hacked his life to create a more youthful appearance.
