Think you could walk across a rope 1,000 feet in the air without a net?  How about overcoming a handicap to become a gold medal athlete?  People have pushed their bodies to pull off amazing feats.  These triumphs were not easy. Often these people had to try and try again.  Some even suffered bone-crushing failures.  But, they kept working until they met their goals.  They could be divers, daredevils, models, or motocross riders.  One thing is for sure-the limits of the human body never stopped them!
