The U.S. Army is often viewed as a no-nonsense organization, as it should be, given the awesome responsibility that lies with its members to protect and defend the people of the United States. As such, military jargon usually reflects this, which words such as, “Roger,” “Affirmative,” and “Execute.” These all conjure up images of hard-bitten soldiers giving orders in combat or communicating vital issues over the radio. And for the most part, this image of a professional organization is exactly correct.
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.
