           One example of extreme sports is bungee jumping. Bungee jumping is very popular among us today. Bungee jumping is a game where we jump from a tall structure using a long large elastic cord. The tall structure must be a fixed object such as building, bridge, crane and so forth. It will be more possible if the structure is movable. This is because people will get scared if the structure moving. Examples of movable high structure are hot air balloon and helicopter. The next example of extreme sports is mountain biking. Mountain biking is the sport of riding bicycles off-road over the rough terrain. We must use the specially designed mountain bikes if we wanna to mountain biking. Mountain biking can generally be broken down into multiple categories. They are cross country, trail riding, all mountain, down hill, free-ride and dirt jumping. Mountain biking requires strength, balance, bike handling skills and self reliance. Mountain biking can be performed everywhere such as backyard, gravel road, back roads, fire roads or single tracks.
