American soldier Travis Mills served three tours in Afghanistan until he lost his arms and legs in a bomb explosion.

The retired United States Army staff sergeant spent months recuperating at Walter Reed National Military Medical Center, but don't dare call him a wounded warrior.

"I'm not wounded any more," he said. "I'm just a guy living life."

Recalling comrades killed in combat, he asks: "How selfish would it be if I gave up?"

Using "neat" prosthetics, he runs, snowboards, and bikes.

This guy's attitude is so inspiring, no matter what your own misfortune may be.
