I'm a duffer and all my friends are duffers. We play fast though, so no hatin'.
Anyway, I played with a friend of a friend one time that is obviously one of those natural athletes. (I considered myself an above average athlete in my younger days. Played point guard in basketball, ran the hurdles and 400 , high jumped and long jumped in track, etc. but wasn't exceptional in any of those.) This guy was just on a completely different level. He played baseball in college (D-I, I believe) and IIRC he played a little semi-pro ball. Hand-eye coordination off any chart I would ever be plotted on, that's for sure. He could do the Tiger Woods bounce-the-ball on the wedge, then swing and hit it. He said, and I believe him, that he won a bet with his brother and Dad that he could get the ball on the green of a par 3 that way, and did it on his first try.
He's a lefty and had just the smoothest swing. He didn't play regularly, and was playing for the first time in a year or more. He never hit a wood. Teed off with his 3 iron on long holes, and was nearly as long as our drivers. Can't remember why he said he didn't use his woods... just didn't like them or didn't want to hit them while rusty, or maybe he was just being nice and not show us all up too much.
He didn't do anything spectacular, but hit nearly every fairway and his approaches were all reasonably close to the pin. His putting was good but he didn't sink a lot of really long ones (I guess he didn't have a lot of those). He shot in the low 80s with what seemed like no effort at all. The rest of us were upper 90s or low 100s. It seemed clear that he could get down to mid-70s with no problem at all, whereas I don't think that's EVER possible for me or my other buddies.
It just pointed out to me that golf is an entirely different game for some than it is for the rest of us. I don't think I could ever be that smooth and repeatable. Over a round, my concentration comes and goes, and my form deteriorates and I have no idea what's going wrong or how to fix it. That guy had a level of muscle memory and control that I just can't comprehend.
