What is the range of art?

I remember getting into an argument with a girlfriend's father about sports, which is probably not a good thing to do, or at least to do frequently.

He didn't like sports much, and considered football players offensive louts, without grace nor skill, and lacking in any aspect of interest to him. The house was often filled with the strains of opera music, and I imagine the television dial was rarely switched from the public television channel to any other.

And I remember thinking during that argument that many arts are performance based, such as ballet, where grace and skill were an important aspect of the artform. Is there a thin dividing line between dance and sports? In some arenas, such as figure skating, it's difficult to draw that line. I'm not calling Terrell Owens a ballerina, but he's as graceful as most folks who walk around this globe.

In the wikipedia article on Artist, the following is from a list there on art and artist. For each of the following, the article also includes an artist name. I removed those, and just listed the "Art."

It's a broader list than I expected, and some of the arts or artist types enumerated are ones that I wouldn't expect. For instance, I'm not sure that I would have put a "Fashion model" on the list. Maybe I'm not being open minded. If in the future I describe a football game as an art performance, I'm storing up an argument.

(I had to look at one of the examples listed in the wikipedia of a neo-figurative artist to see what that was exactly - Fernando Botero)

So, if you do something with a flair that can't just be influenced by the utility of the moment, that makes you an artist? (Maybe I'm getting this wrong.)
