Consider the wartime love letter: a tradition of military service, a downrange sufferer’s record of affection and longing, sent home to a waiting love, often saved by the receiver for posterity.
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.
And no one knows that better than military service members and we have the pictures to prove it.
