It's common knowledge that Secretary of Defense James Mattis embodies the humility and empathy we've come to expect from modern military leaders. He does laundry in the Pentagon basement, forgoes appearances on cable news, and praises the U.S. service members under his responsibility at every possible moment.
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.
