KABUL, Afghanistan  It looked like an ordinary neighborhood playground: six children tumbling off their skateboards to the tune of laughter. But only hours before, just 20 yards away, the body of a suicide car bomber was sprawled beside a glistening pool of blood.

Afghan youth have learned to recover almost instantly from such routine violence. One person determined to inject some normalcy into their lives is Oliver Percovich. A 34-year-old from Melbourne, Australia, he plans to open this country’s first skateboarding school, Skateistan, this spring. He sees sport as a way to woo students into after-school activities like English and computer classes, which are otherwise reserved for the elite.

“Teenagers are trying to dissociate from old mentalities, and I’m their servant,” Percovich said. “If they weren’t interested, I would’ve left a long time ago.”

Now, when he pulls his motorcycle into a residential courtyard here, a dozen youngsters pounce before it comes to a stop, yanking six chipped skateboards with fading paint off the back. The children, most participating in a sport for the first time in their war-hardened lives, do not want to waste any time.
