There are many types of hobbies. Some of them are strange, such as piercing your skin with huge metal hooks with ropes attached to them, and dangling yourself from the ceiling. Others might enjoy riding down huge mountain hills on skis, snowboards, mountain boards, bikes, etc. However, some enjoy pastimes that are more tranquil and meditative. For example, the art of contortionism is a very peculiar hobby that is usually practiced by women and children, due to the natural stretchiness of their tendons. Despite the fact that tendons of grown men are usually too stiff, a Berlin-based dancer is able to do amazing things with his body and is not afraid to show it to the world.

Beach racing is an offshoot of enduro and motocross racing. Riders on solo motorcycles and quad bikes compete on a course marked out on a beach, with man- made jumps and sand dunes being constructed to make the course tougher.
