ode I live in a 55 plus golf community. The course is somewhat difficult due to the greens and what you face when you miss them. It’s amazing how many guys here can shoot their age. These guys have probably always had good swings. They are also good putters and chippers.
We have the occasional 80+ year old who does it. And the occasional early 70s. But mostly they are between the ages of say 73 to 78. Like @fatshot . That seems to be the sweet spot.
I’m sure it helps that these guys play the same course 150 times a year, if not more.
