Starting in 1982, he made the final keystroke on December 7, 1998. Les needed typing skills for a job in the police force, and the tenacious typist remembers sitting down in front of his first typewriter. "I just had a feeling I could break a record on it," he says. Les turned out to be a whiz on the keyboard and was soon promoted to typing instructor. "I had a reputation for being the tidiest and neatest typist in the force," he recalls. Contracting encephalitis in Vietnam left Les seriously ill and partially paralyzed. His employers told him he was too sick to continue work. At this point Les decided to focus all his reserves of discipline and determination on breaking a record. He could still type, but only with one finger, so he began the massive milliondigit march to a world record. By the time Les finally typed "one million" he had exhausted seven typewriters, 1,000 ink ribbons, and almost 20,000 sheets of paper. "All I was concerned with was crossing the finishing line," says Les. "I was so positive, I just had to keep the momentum going." The pressure began to mount as Les approached the monumental million. "I realized I would soon have to face the world," he recalls. Journalists and TV crews crowded the living room as Les began the final day of his typing marathon.
