[quote name='Temporaryscars']I'd say what about bowling, surfing and skateboarding, but I'm not convinced they're sports. More like hobbies.[/quote]
They are not sports.
The only way to be a sports is if its one human body (or a team of human bodies) competing against one or another group of human bodies within the same plane and includes some type of offense and defense.
Things like Chearleading, Nascar, Dancing not sports.
Things like, Ping Pong, Boxing, Track are sports.
Then there is baseball....which is just barely a sport at all.
