What is a sport? Does it have to be a physical activity or something competitive? I believe that a sport is anything that you have to practice to be good at. Also i believe that it has to demand at least a little physical activity. The majority of sports are played competitively or almost at all times for ones entertainment.  Many sports require the participants to obtain  a cretin skill set and to put in the practice needed to become better. 

There are many activities that can be considered a sport. A sport can be anything from hunting to skiing down a mountain. There are millions of people that dedicate their lives to a sport that they fall in love with. Because of the fact that people play many different sports competitively does not mean that others don't do it to have fun and enjoy their time. Anything you do in life might involve you practicing to enrich your ability to complete that task. Now weather that task is shooting a hockey puck or driving a race car   practicing will make you better.
