Vancouver, British Columbia (CNN) -- Many kids dream of being in the Olympics one day. When U.S. bobsledder Bill Schuffenhauer was a child in Salt Lake City, Utah, he had no idea the Olympics even existed. All he knew was his parents were drug addicts, that his mother was a prostitute who was often beaten in front of him. He knew that if he was going to survive, he had to do whatever it took to make it. He stole from people; he ate from garbage cans; he got locked up in juvenile detention for breaking into a bike shop when he was trying to get something he could sell for money so he could eat.As a child, bobsledder Bill Schuffenhauer often lived on the streetsHis mother and stepfather were addictsHe turned to athletics in junior high and became a star decathleteAfter his track career ended, he tried out and made bobsled team that won silver in 2002
