Lincoln DeWitt always tries to keep his chin up. That's tricky, especially while zipping down an icy track at a bone-chilling speed of 80 miles per hourheadfirst! DeWitt, 34, is a top U.S. contender in a sport called skeleton, a high-speed race down a bobsled chute. The sport, named for the sled's bony framework, has only been in the Olympics twice: in 1928 and 1948. The 2002 Games mark its Olympic return. "If you like things that go fast, there's nothing better," says DeWitt. He first tried skeleton five years ago, after the Olympic track opened near his Park City, Utah, home. His life took a sharp turn last year when he left his job to train full-time. It paid off. Last season, he became world champ!
