Some are excited about expensive champagne, others like jumping off a tall building. In the history of mankind, there have existed many ways to test nasty ways to die in the form of extreme sports.
A sport is catalogued as extreme by the worst case scenario, when something goes wrong. If the person has to use special equipment to control an incontrollable and unpredictable environment, thus being exposed to the elements, it is considered as an extreme sport. Cave diving in enclosed and dark spaces is definitely one of the activities that attract men and women in their late 20s until the early 40s, who like to live for the moment, as it can be their last. Scuba diving, which stands for a self-contained underwater breathing apparatus, offers great views of the ocean environment, but being one with the fish has its drawbacks. If one ascends too fast, one can suffer decompression illness which can cause failure of the spinal cord, brain and lungs. The sharks or the jellyfishes around the diver are other treats that ask for a good travel and health insurance.
Despite these threats, the Professional Association of Diving Instructors, or PADI, and Scuba Schools International, or SSI offer open sea diving certifications for prices that vary from $150 to $600. The demand is big, as there are many enthusiasts. The most famous locations for learning scuba diving are Florida and California in the US, Mexico and Egypt.
Getting lost or separated from the diving crew, hypothermia, low visibility, lighting failure and air loss are some of the most frequent threats of this beautiful and extreme sport. A successful dive is one that you return from, agree the divers from The National Speleological Society. The diving threats are even higher when exploring caves, as you cannot just come up for the air, as in the open sea diving, because you might just smash your head in the stalactites.
