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.
A few months ago, I read Phil Klay’s book, “Redeployment” — a collection of a dozen short stories. One of its unifying themes was that young people, and young men in particular, seek validation through combat. There are myriad consequences to facing combat — some good, and others bad. Others who never face combat, but expected to, are often left with intermingled senses of regret and embarrassment. There’s a selfishness in the sentiment: service is about “We.” Validation, potential regret, and its attendant embarrassment are about “Me.”
