Now 72 years old, Jack Nicklaus jokes that he can't remember what happened yesterday.

Yet he's never forgotten what it was like to hit the most famous shots of his illustrious career.

Speaking Monday at a charity luncheon affiliated with his Memorial Tournament, Nicklaus said he's never lost the feel of the 1-iron that he hit off the pin to take the 1972 U.S. Open at Pebble Beach, or the 5-iron at 16 that helped him win the 1986 Masters.

Even though he no longer plays much golf he said it's remains a lot of fun that he can readily summon how it felt to strike some of the signature shots in the game.
