Before Bubba Wallace, Bill Lester was the last driver to compete on a regular basis at the top levels of NASCAR – that was in the early 2000s. Lester tells CBS News' Jericka Duncan why he decided to pursue a career in racing in his late 30s after a successful career as an engineer at Hewlett Packard. Lester's new memoir is Winning in Reverse Defying the Odds and Achieving Dreams, which is published by Pegasus, an imprint of Simon and Schuster, a division of ViacomCBS.
