David Schmidt,
Of course you are right regarding "ability" in the literal sense. However, in the context of golf and the way most people approach and play the game, I think Mr. Mucci's referenced comments are insightful and particularly relevant.
I got "into" golf as a result of going to Ohio State and having the Scarlet course available to me for less than $100 per year. Having Tom Weiskopf and Ed Sneed around to observe closely- I've practiced next to them on several occasions- served to reinforce the physicality of the sport with a beautiful, delicate rythm and tempo that I hadn't seen in other sports.
Though Nicklaus (who I saw in Columbus numerous times but never hitting a ball at OSU) spoke of the thinking side of the game and his mental toughness and discipline were frequently cited for his outstanding performance, most of us so struggle with the physical aspects to the extent that we never get to the other part. It is the mental side of golf that Patrick speaks about, and though this too is part of one's "ability", I think it is one that is not typically associated in practice (as opposed to theory) when most of us play golf.
A sad fact of the cycle of life, particularly for those of us on the long side, is that our physical abilities diminish. Disease and injuries can hasten that process, but often our brains are not badly affected in the areas that can help us overcome the loss of physicality. Understanding gca, devising good strategies, learning to hit effective shots with whatever limited range of motion we might have, etc. are the things that I found meaningful in the aforementioned piece, and that can bring new interest, excitement, and joy to our game even when we can't hit the shots we can still remember.
One last thing about quitting because one can't play like he used to, and my apologies if this gets too close to home. I think I was with you when you got the call that your father was ill and you had to leave the KP match abruptly to return home. You had previously told me about his condition and that he had quit the game at a relatively early age- if I remember right, in his late 40s to early 50s- because he could no longer play like he used to. I sensed sadness and regret as you related the story, and as I saw you leave Rustic Canyon, I was saddened that you didn't have the opportunity to enjoy this great game longer with the great man.
I've never met Patrick Mucci, but it is obvious that he enjoys golf in some very existential ways. I am sure that his family and friends are fortunate that he finds such joy in his game even when he probably doesn't often play anywhere close to the level he once did. I hope that when it is my time, that my son will be able to remember our last round in the not too distant past.
