It's really not that different from watching sports [i]in principle[/i], if you think about it. If you enjoy doing something, you might also enjoy watching someone better than you do that thing at a higher level. Examples: I like to play baseball. I occasionally watch professional baseball. I like to cook. I sometimes watch cooking shows with my favorite chefs. I like painting and sculpture. I might enjoy watching a famous artists create art. The same idea can be applied to music, science, games, and any other hobbies that people have. It's just about personal differences and what you personally enjoy doing in your free time.
