Jack Nicklaus

Nicklaus has never really retired from the game of golf—he simply matriculated into the Seniors Tournament, winning several of the Senior majors and many of the lesser tournaments. (Nicklaus himself said once that the majors "are the only ones that count.") He continues to win occasionally on the Senior tour, but he does not play as often because, upon leaving the PGA tour, Nicklaus in turn increased his input into his business, Golden Bear International (of which he is chairman). The business allows him to manage his many businesses, all of which relate to golf or sports in some way. Nicklaus is well known for his golf course design, with over 150 courses worldwide designed and built by Nicklaus' firm. Of the top 100 courses in the country, 12 have been designed and built by Nicklaus.
