Please tell me how the topic of Scuba Diving fits the definition of sport from dictionary.com is:
- an athletic activity requiring skill or physical prowess and often of a competitive nature, as racing, baseball, tennis, golf, bowling, wrestling, boxing, hunting, fishing, etc. 2. a particular form of this, especially in the out of doors. 3. diversion; recreation; pleasant pastime. 4. jest; fun; mirth; pleasantry: What he said in sport was taken seriously. 5. mockery; ridicule; derision: They made sport of him.
I can not, it is a hobby recreational activity that should stand in its own right.
