1. BASE JUMPING

One of the most dangerous sports. A distinctive feature of base jumping is that jumps are made from low altitudes and athletes do not have much time left to choose the correct body position when opening the parachute. The price of any mistake or delay is too high. Independent attempts, as a rule, lead to serious injuries or death.

2.CAVE DIVING

Diving in caves. At first glance, there is nothing complicated here, but in fact, such a dive can be extremely dangerous. Sometimes swimmers have to make their way in pitch darkness, and in case of danger it can be difficult to climb up.
