I read about a study that claims gamers (and other hobbyists) get worried when they spend more than 20 hours per week gaming. Apparently people have a built-in anti-obsession mechanism that starts sounding alarm bells whenever we get too involved with something, and 20 hours per week is that line for most people.
People who don't have that mechanism tend to become obsessive about their hobbies.
Not sure why I thought that is important, but I think it may be of relevance to you ;)
