I have a friend of mine who took up the game in his early 40's and within a couple of years was a scratch golfer. IMHO, golf is unlike other sports. It does not require the physical stamina of basketball, baseball or football. I cannot imagine playing full court basketball at my age (over 50) and competing with men in their 20's. Golf requires clearly the talent, but also the mental ability to remain focused and not get flustered by a bad stroke or hole. There is a psychological dimension that is very unique to the game. This is not only about avoiding bunkers and water. This is about strategic thinking.
Although there are many professionals who began playing when very young, that does not preclude the possibility that someone who begins playing the game in his late 20's, 30's or 40's cannot become a professional golfer. It will require a significant time commitment to learn the game at a much deeper level than the average weekend golfer who just want to enjoy a round or two. Yes, I do believe that a younger person has an advantage with things like muscle memory, but a seasoned adult is not incapable of evolving and improving his swing.
Above all, what percentages of players who start young actually do become pros? It is so minuscule that it is not statistically significant versus older adults who desire to become professional (I mean make it a life goal and not a daydream) which has to be a small group. If a person later in life comes to discover that golf is his passion and wishes to become a professional, he need not keep it a dream if he is willing to do what it takes. Why not go for it?
