^nbsp;Injury is not only possible but probable. In the face of this risk, the athlete's heart pounds with excitement, and the thought of turning back is overcome by the anticipation of the thrill ahead. The skateboarder runs his skateboard up the ramp, somersaults in the air, and slams back down at incredible speeds. A young woman stands on the span of a bridge that looms hundreds of feet high. When she jumps, she is counting on her parachute to carry her away from the bridge instead of slamming her into its concrete foundation. She hopes to race toward the ground at speeds over 60 miles an hour, and she plans to pull the cord in just enough time to swoop gently to the ground. She is BASE jumping.
