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.
