At first glance, Jim Russ seems to be an unlikely person to write about life in the past, present and future. He graduated from Norwich University, a military college in Vermont, and received a Bachelor of Science degree in mathematics. Before going into civilian life, he received an officer's commission in the US Army, where he spent four years on active duty and a number of years subsequently in the US Army Reserve. After his military service, he worked in IT for 22 years until retirement in 2015. It was his great curiosity about this subject that drove him to explore all the mysteries of life in his retirement. It was a quest worth taking for this ordinary man.
