Jack Nicklaus turns 80 on Tuesday and has no interest in retirement. Nicklaus stopped competing long ago except for the occasional exhibition. He keeps involved with golf course design and helping wife Barbara with the Nicklaus Children's Health Care Foundation. What he really enjoys is staying relevant. He says he is flattered by the number of young players who want to spend time with him and ask questions about the majors. Also keeping him relevant is Tiger Woods and the chase to match the 18 majors Nicklaus won in his career.
