Alpinism is one of the extreme sports, and includes climbing high hills and mountains with not so serious safety equipment. Anybody with a normal level of adrenalin would never do such a thing knowing the risk of this sport, but these photos show that there are people who enjoy being on the edge of life or cliff and even taking pictures. If you ask me, it would be interesting to try, only once perhaps, just to experience the feeling of being up there, but of course knowing nothing can happen to you
