It's an emotional experience. You cannot rationally derive human emotions, and you won't be able to rationally justify the things people have come up with to serve emotional needs (see e.g. military drills, which look nuts to observers). So you might as well take other people's preferences for activities as evidence that there is a reason to prefer them.
