(10 points).There’s a condition in combat that occurs when a soldier is completely stressed out and is “on the verge of a nervous collapse.” In World War I it was called “shell shock.” Simple, honest, direct language. Two syllables. Shell shock. It almost sounds like the guns themselves . . .. . . [I]n World War II the same combat condition was called “battle fatigue.” Four syllables now; takes a little longer to say. Doesn’t seem to hurt as much . . .By the . . . Korean War . . . the very same condition was being called “operational exhaustion.” The phrase was up to eight syllables now, and any last traces of humanity had been completely squeezed out of it. . . .Then . . . we got into Vietnam, and, thanks to the deceptions surrounding that war, it’s no surprise that the very same condition was referred to as “post-traumatic stress disorder.” Still eight syllables, but we’ve added a hyphen, and the pain is completely buried under jargon . . . I’ll bet if they had still been calling it “shell shock,” some of those Vietnam veterans might have received the attention they needed.
