Bob -
I don't know what it will take for me to quit, or when that will happen. I'm guessing it's a much harder decision for those who once played the game very well. They'd feel/experience the decline more acutely than most, but would likely have had many more years of pleasant associations tied to the game.
John Barrymore once said "A man is old only when regrets take the place of his dreams."
Thanks for the article on Mr. Longhurst. Do you remember the 75 Masters: Weiskopf makes the putt on 15 and Ben Wright says "Ah, evil music to the ears of Mr. Nicklaus". But then Jack drills in his 40 footer on 16, and Henry Longhurst says "And now, young Mr. Weiskopf will have to take it, just as he dished it out". Great stuff. Maybe more announcers should take up drinking to excess...
