Hobbies are an interesting thing.
I have tons of interests, but they aren't all important. Certain interests can become important in specific situations.
Take my fondness for volleyball. At the moment, I don't play any volleyball, so this interest is not particularly important. But 3 years ago, it was pretty much all I did all week every week.
It's really hard to sit up straight for long periods of time. Say, longer than a minute.
