Several years ago, the satirical newspaper The Onion ran an article about "Pre-Traumatic Stress Disorder," based on a "study" by the Department of Future Veterans Affairs. Victims of the disorder, according to the report, experience "vivid, ultra-realistic flash-forwards" of disturbing wartime events that are yet to come. Soldiers who have never experienced a day of battle nevertheless "prelive" the hell of war.
The story was irreverent and no doubt offensive to some, but it was funny. It was funny because the whole idea of remembering the future is absurd.
