Goes for any sport, or activity we do for fun. I wasn't saying golf isn't a sport. I meant anything we do as a leisure activity, including all the sports we play. It can be basketball, hockey, softball, golf, or whatever. We're all armatures just doing them for fun. I said "X" in my original post because I think it applies to all sports.
Why anyone would risk permanent injury for that is what I don't understand.
If golfing, or that sport you may hurt yourself in, is part of your livlihood, than it becomes a different consideration.
