The other day, I was watching a football game I had recorded last season and taking notes (I like to be informed when I discuss football) when my wife came downstairs and gave me this disgusted look, as though I was doing something personally offensive to her. If I was just sitting around watching TV, she probably wouldn't have cared, but for some reason, rewatching a football game is unacceptable. It got me thinking, though. Why are some hobbies considered "normal" and others are not? Why are some considered better than others? Why should a person really care how another person spends their free time? As an example, in general, people consider reading a book to be better than watching television. But why? I understand the reasoning for kids, since reading comprehension is definitely an ability requiring practice and necessary to develop certain skills necessary to become a productive member of society. However, if a college-educated adult wants to spend 4 hours a day watching TV, how is this worse than reading a book for 4 hours a day. You can definitely learn more in less time. They can both cause eye strain. Neither one is particularly healthy, in regard to requiring physical activity. But reading is considered "good" while TV-watching is considered "bad." So I was wondering what other people thought on this. Assuming that any particular hobby won't be used for productive purposes in the future, why are some better than others? Are there other examples you can think of? I'm curious to know how other people feel about this subject.
