Excellent point. My much younger brother runs cross country in high school. He loves running and it's great that he found a hobby he enjoys, but the problem is that he doesn't see it as a hobby. He thinks that participating in sports is making some kind of noble sacrifice for the greater good. At my parent's house he expects everyone else to sacrifice to enable him to participate, e.g., he is tired from running so someone else has to do his chores. He's been taught by his coaches that what he does isn't recreation, it's a glorious pursuit that benefits everyone else.
