You read spellbound as young JFK swims miles behind enemy lines in shark infested waters with the life jacket strap of his oldest and most injured crew member clinched in his teeth, leading his sailors to safety on a deserted island.
He goes back out alone in the black sea, treading water for hours hoping to flag down a passing American ship. JFK was only 25 years old, on his own, having volunteered for combat. Years later he kept a glass paperweight on his desk in the oval office that contained the coconut that he had carved a message in and sent to his base alerting his commander to his crew's location.
