I’d wager that almost every vet (well, at least those who served in the Army), have a better understanding of logistics than the average civilian. Even though my role in the Army was intelligence, I still had to do logistics, from planning field exercises for my soldiers as a platoon leader, to equipping a company when I was an executive officer. We planned and executed the movement of people and equipment on a daily basis — all aspects of logistics.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
