Do not doubt your eyes. Diving has been officially listed as one of the extreme sports. It challenges how far humans can go in the underwater world. Diving and leisure in our daily life seems to have nothing to do with challenging physical limits, but the dangers we face are the same. Jose, the lover of Taiwan Province woman writer Sanmao, had an accident while diving in Palma Island.

Second place bungee jumping:

Bungee jumping originated in Vanuatu Islands in the Pacific Ocean, and it is a rite of passage for local youth. There is a small island in Vanuatu called Pentecote, where residents hold a "death jump" every April and May. The boys tied a crutch to their feet and then jumped off the "platform" more than 30 meters high, proving that they have become adults who can face danger alone.

The danger of bungee jumping is equivalent to driving a car with a speed of 160 km/h. From a medical point of view, bungee jumping has several potential threats to human body: first, during falling, subretinal capillaries are easy to rupture, leading to temporary blindness; Second, in the process of falling at high speed, you accidentally hit a mountain, a branch or a rope tied to your foot, which may cause fractures and quadriplegia, and in severe cases, you will be disabled for life; Third, other potential injuries that have not been discovered and confirmed. In addition, bungee jumping equipment lacks maintenance, improper debugging, extended service, or the staff lacks necessary training and experience. Clubs or companies that operate bungee jumping fail to comply with the necessary safety regulations, and even play this life-and-death game without obtaining legal business qualifications at all, which are the root causes of accidents. For those who are keen on this kind of "death" game, bungee jumping needs not only a strong heart and good blood vessels, but also good luck.

No.3 foundation jump:

Bottom jump is a gliding event in extreme sports, which is more dangerous than skydiving. Bottom jump is generally jumping on fixed objects such as tall buildings, cliffs, towers and bridges. Because of the limited distance, it only takes 5 seconds to open the umbrella bag, so it is difficult to adjust the posture and movement in the air. Only experienced parachutists can go to the base to jump, but there is no guarantee of foolproof. On June 5, 2004, Roland Simpson, an Australian skydiving expert, jumped from the skydiving point 345 meters away from Shanghai Jinmao Tower, but the parachute failed to open for the first time. When the parachute finally opened, Simpson was close to the ground. He didn't land on the designated lawn, but was blown to the podium by the wind and was seriously injured.

No.4 flying at high altitude:

Since Mr. Ke Shouliang, the first pilot in Asia, successfully flew over the Yellow River in a Mitsubishi sports car in 1997, it seems that high-altitude leap has become a popular occupation. Some flew over Hukou, some flew over Chuhan Honggou, another participant bravely flew over Chuhan Honggou, and another participant fell down heroically in the process of flying over the Great Wall. His mount turned out to be a bicycle.

Jumping at high altitude is an extreme life sport. It takes courage to engage in this sport, but the most important thing is to rely on the protection of cutting-edge technology. When Mr. Ke leaps over the Yellow River, his sports car has great power and can accelerate to 150 km in a short time. In order to prevent accidental damage and explosion of the car body, the car is equipped with a 3-second automatic flameout device. There is also a perfect computer system and automatic operation device in the car, which can cope with all kinds of possible accidents. If there is no such security, I advise you not to play this dangerous game.

No.5 high-speed racing car:

Driving a racing car with a speed of 300 kilometers per hour on the runway and feeling the perfect combination of man and machinery in the limit of speed is really an exciting and wonderful experience. In the process of high-speed racing, the challenge is of course the driver's skill and reaction speed, but human beings are also playing a dangerous game with death while challenging. 12 years ago, the car god Senna was driving Williams into the fifth lap of the race. Suddenly, the car lost control and ran into a concrete wall. The car body was torn in the violent impact and overturning, and a wheel went straight into the sky like a toy frisbee ... The whole process was only a short 10 second, and a generation of car gods died after 10 second.

Extreme sports seem to have become a fashion, which requires high physical strength, courage, physical coordination and flexibility. Nowadays, it has become a popular outdoor extreme sports choice, which is undoubtedly dangerous for those who have not received professional training.

Sixth place freehand rock climbing

Rock climbing originated in Europe in18th century and became an independent sport in 1970. Freehand rock climbing refers to the process that climbers climb by their own strength without relying on any external auxiliary forces. Freehand rock climbing requires people to continuously complete turning, pull-ups, prancing and even jumping on rock walls of various heights and angles, which integrates fitness, entertainment and competition. It is an exciting and beautiful extreme sport, which is called "ballet on the cliff" by rock climbers all over the world. Although in recent years, rock climbing has gradually become a popular outdoor extreme sport, and more and more people have experienced unique fun from rock climbing, freehand rock climbing requires extremely high physical quality, courage, physical coordination and flexibility. For novices who have not received systematic professional training,

Seventh place mountaineering:

Mountaineering is definitely the most vivid example of human beings challenging nature. The cultivation of physical fitness, the adjustment of breathing methods and footwork are all indispensable and valuable experiences to impact the limit of physical fitness. All this comes from the training of system specialty, and it is undoubtedly dangerous to try to bypass this process. A few years ago, amateur mountaineers died one after another, which was an extremely painful lesson. Mountaineering needs to respect science and be carried out under the strict guidance of scientific training law. Climbers must undergo special training and be fully prepared in knowledge, physical fitness and equipment, and must not blindly take risks just because they are young and energetic.

Eighth, survival in the wild:

I don't know why modern people like this kind of leisure, but comfort is a kind of comfort. But the rules of the game in the jungle and Shan Ye are not something that can be clearly explained by one or two so-called "survival guides in the wild". Once a crisis occurs, there are only two choices, either waiting for help or facing death.

No.9 downhill skiing:

Of all the land gliding sports, downhill skiing is of course one of the events closest to extreme sports. Downhill skiing is fast and changeable, and the body is integrated with nature, which gives people excitement and enjoyment. People can't help but pursue and participate, ignoring their own safety, which is the most dangerous problem in downhill skiing. Downhill skiing can easily make people get excited unconsciously, especially young people, who often accelerate regardless of their own technical deficiencies. At this time, it is not only easy to hurt yourself, but also to other skiers. In addition, if you are not fully prepared, unfamiliar with the terrain, lack of sleep or poor physical condition, it will become a potential danger inducement.

No. 10 Hunger and Cold Tolerance:

David Bryant, a 30-year-old American magician, challenged extreme sports for 44 consecutive days, spending 44 days alone in a large glass box hanging by the Thames in London, without eating any food but drinking water.

This is an event that has not been mentioned in extreme sports, but it seems to have become a fashion with a series of actions to challenge hunger. I can't imagine what kind of extreme challenge this is, but relatively speaking, in everyone's eyes, this is the only sport that is not life-threatening.

Extreme sports seem to have become a fashion, which requires high physical strength, courage, physical coordination and flexibility, and has become a popular outdoor extreme sports choice. It is undoubtedly dangerous for people who have not received professional training.
