An extreme sport is usually defined as one that requires extreme levels of endurance, balance, skill, co-ordination; also, ballistic reaction timings, spacial orientation abilities, and massive amounts of oxygen assimilation. Extreme sports are dominated by youth, age range 6 to mid 30's. The first recognized extreme sports, were officially documented by the Post Office commissioning of a stamp series highlighting the first three: Skateboarding, Snowboarding, and BMX bike riding. Since that time, several others have been added to include, Inline Rollerblading and Motocross.

As opposed to friends who actually use facebook as a social utility, sports-bookers are those facebook friends of yours that treat their profile like it's their own personal sports blog.

A predominantly competitive (comparison or self-evaluative) activity within which the participant is subjected to natural or unusual physical demands. Moreover, an unsuccessful outcome is likely to result in the injury or fatality of the participant, in contrast to non-extreme sport. -Cohen, Baluch and Duffy
