There are many reasons why people golf. I could make a list of cool reasons or excuses why people golf, but that would just be silly. Everyone has their own reasons for golfing and enjoying their time on the links.
There are challenges with golfing too much or not having a reason to hit the course, but that is a rare thing. Sometimes, golfers go to the course because they have nothing else to do and I guess that is as good a reason as any. However, sometimes we golf for the sake of golfing!
