One reson why golf isnt a sport is because there isnt compitision in golf when if you look it up it will say that the meaning of a sport is if there is compitision.
(This isnt a reson) Golf isnt that active because you dont move that much becuase you use a golfcart to get arround.
With that being said there may be the agument that "Well what about PGA", Wellllllllllllllllllllllllllllllllllllllll its still not a sport nice try :)
The picture kinda looks like Bill Gates.
