When you are standing in the 40 meters high places, both sides are Castle Peak and cypresses.Endless flowing river is under your feet, you have to jump from here after a few seconds.How is your feeling?Perhaps your heart beating violently, your legs are shaking hard, but after you jump,the satisfaction of falling is really exciting.And now ,you are the hero!

History
The word “bungee” originates from West Country dialect, meaning “Anything thick and squat”,as defined by James Jennings in his book “Observations of Some of the Dialects in The West of England” published 1825. Around 1930 the name became used for a rubber eraser. The word bungy, as used by A J Hackett, is “Kiwi slang for an Elastic Strap”.Cloth-covered rubber cords with hooks on the ends have been available for decades under the generic name bungy cords.
In the 1950s David Attenborough and a BBC film crew brought back footage of the “land divers” (known as “Naghol”) of Pentecost Island in Vanuatu, young men who jumped from tall wooden platforms with vines tied to their ankles as a test of their courage and passage into manhood.A similar practice, only with a much slower pace for falling, has been practised as the Danza de los Voladores de Papantla or the ‘Papantla flyers’ of central Mexico, a tradition dating back to the days of the Aztecs.
A tower 4,000 feet (1,200 m) high with a system to drop a “car” suspended by a cable of “best rubber” was proposed for the Chicago World Fair, 1892-1893. The car, seating two hundred people, would be shoved from a platform on the tower and then bounce to a stop. The designer engineer suggested that for safety the ground below “be covered with eight feet of feather bedding”. The proposal was declined by the Fair’s organizers.
Bungee at Kawarau BridgeThe first modern bungee jumps were made on 1 April 1979 from the 250-foot (76 m) Clifton Suspension Bridge in Bristol, by members of the Oxford University Dangerous Sports Club. The jumpers were arrested shortly after, but continued with jumps in the US from the Golden Gate and Royal Gorge bridges, (this last jump sponsored by and televised on the American program That’s Incredible) spreading the concept worldwide. By 1982 they were jumping from mobile cranes and hot air balloons.
Commercial bungee jumping began with the New Zealander, A J Hackett, who made his first jump from Auckland’s Greenhithe Bridge in 1986.[8] During the following years Hackett performed a number of jumps from bridges and other structures (including the Eiffel Tower), building public interest in the sport, and opening the world’s first permanent commercial bungee site; the Kawarau Bridge Bungy at Queenstown in the South Island of New Zealand.[9] Hackett remains one of the largest commercial operators, with concerns in several countries.
Despite the inherent danger of jumping from a great height, several million successful jumps have taken place since 1980. This is attributable to bungee operators rigorously conforming to standards and guidelines governing jumps, such as double checking calculations and fittings for every jump. As with any sport, injuries can still occur (see below), and there have been fatalities. A relatively common mistake in fatality cases is to use a cord that is too long. The cord should be substantially shorter than the height of the jumping platform to allow it room to stretch. When the cord reaches its natural length the jumper either starts to slow down or keeps accelerating depending upon the speed of descent. One may not even start to slow until the cord has been stretched a significant amount, because the cord’s resistance to distortion is zero at the natural length, and increases only gradually after, taking some time to even equal the jumper’s weight. See also Potential energy for a discussion of the spring constant and the force required to distort bungee cords and other spring-like objects.
Safety and Equipment
Most deaths from bungee jumping occur because harnesses were not put on correctly. Therefore, it is important to have professionals help you put on your harness even if you are not a beginner. That means that you should go to a company or a club that specializes in bungee jumping. Make sure the club is certified by a government agency, such as the Occupational Safety and Health Administration or the British Elastic Rope Sports Association.
One of the most important services clubs provide is taking your height and weight measurements. This helps them fit equipment properly.
Ankle harnesses are usually secured to both legs, and they are often used in conjunction with other harnesses, especially body harnesses. When using ankle harnesses, it is best to have your body facing the line of the cord, especially when the cord becomes tight, or you could risk breaking your ankles.
Body harnesses are often attached to the stomach area to allow people freedom of movement with their arms and legs. This type of harness is similar to what people use when they are climbing. Another type of harness is the shoulder, or arm, harness. However, this should not be used by itself. Doing so would put your full weight on your arms, which could lead to a shoulder dislocation or other arm injury.
Along with fitting harnesses, professionals take steps to ensure a location is safe for jumping. Such work includes ensuring that the bungee cord is anchored properly and other equipment, including airbags, is used as needed.
For a safe jump, it is essential that the bungee cord is tied off in a secure location, one that is stable and will not be affected by added weight. Steel railings or safety fences often make good places from which to anchor. Professionals also will make sure that the bungee cord is tied with weight-bearing knots that will stay in place when gravity is pulling jumpers downward.
In some locations, companies may place airbags, webbing or slings at the bottom of a jump space to guarantee the safety of jumpers. For inexperienced jumpers, locations with airbags and webbing can provide a safer place to start.
Some companies may call off jumps due to inclement weather: Equipment may not work properly in rain, snow and other types of weather. Poor visibility and unstable wind conditions also increase the risk of injury.
Pop Culture
Bungee jumping scenes can be found in many major motion pictures, including “GoldenEye” and “Selena.” Bungee jumping also has been part of television shows, especially reality shows such as MTV’s “Road Rules.” Bungee trampolines, which are found at community fairs and midways, allow a participant to jump on a trampoline while getting a boost from attached bungee cords.
Warning
There are many possible bungee jumping injuries. Miscalculating a cord’s elasticity, a faulty harness, or an improper connection to the jump platform can all cause injury. A bungee jumper can get hurt if the cord gets tangled with his body. A jumper may suffer rope burn, dislocated joints, bruises, whiplash, pinched fingers and injuries to his back. There have been several deaths attributed to bungee jumping.If you are elderly, children, pregnant women, patients, please do not try.
