I know that Golf is incredibly difficult, and I do play myself, I thank you very much.
Its definitely tough, but I don't think you will find a single human being on the planet that wouldn't call it a Leisure sport when compared to the violent sport of Football.
Maybe I spoke too highly when I said "the tour", what I really meant is "professionally" in any arena. He has enough money to retire now, so why not take up Golf? If he plays football for another 5-10 years, he MAY not be able to walk when he's 55.
No sir, I am not being funny. I was actually serious.
