No, it's not amazing at all. What's the point of distinction (read: how can it be abused) between picture #1 and picture #4?
And, look at the background in picture #1. Most telling, isn't it? I see trees, and lawn, and sky, and... outdoors.
I guarantee you that you don't get the same workout playing pool as you do golfing (I do both). I live right next to the renowned
Centennial Golf course here in Putnam County. With a big windup, I can just about sidearm a stone from outside my front door and chip it into a hole. I see golfers every day, and they are FAR more exerted than any pool player. And if you are
that exerted playing pool, I would suggest getting a physical exam ASAP, because something's wrong with you. The notion that "playing pool = 18 holes of golf" is laughable. Sorry.
The golf dress code reflects the activity -- which is not only a ton of long-stride walking (more than pool, no matter what your pedometer says), and a lot of swinging -- hard -- compared to the putting. All outdoors, btw. As one other poster mentioned, miniature golf is more akin to pool than real golf is.
