Mark, as a guy whose body doesn't do what it used to (and has punished me with repeated injury for trying to force it to), I give the idea a big thumbs up.
I'd also add that I think distance is overrated. Maybe that's my jealousy in not being able to throw 400-500 ft. or further, but I've come to realize that accuracy, course management, putting, and shot making are infinitely more important. I think most people would, on paper, agree with this. Yet if you look at the bulk of this forum almost all talk of technique is about distance, snap, and throwing far.
Hopefully older also = wiser. And I think the wiser players benefit much more from the other aspects of the game than distance. I can relate this to ball golf pretty well. All ball golfers have played with that older guy who the starter put in their group. He hits it 200 yds arrow straight, is deadly around the green and out of the sand, and can putt lights out. His game goes like this: 200 yds straight, 200 yds straight on the green 2 putt, par; 200 yds straight, 150 yards, chip, putt, par; 200 yds straight, 150 yds on, putt, birdie; and so on. Meanwhile you are trying to kill yourself on every shot especially the drives. At the end of the round, you shoot a 90 (well I do anyway), he shoots a 75.
I can think of only a handful of holes near me where sheer distance gains strokes. I can think of countless holes where accuracy with moderate distance gains tons of strokes. Don't get me wrong, I'd love to be able to throw further, but there is no reason in my mind to kill my aging body trying to throw super far. I reap far greater rewards working on other stuff.
