Sylvester Stallone is an absolute cliffhanger master in the film Cliffhanger, but that’s just Hollywood. Some other people, non-celebrity characters, are so full of adrenaline that they decide to camp hanging on the cliffs and steep mountain edges. They do not find it abnormal to perform some common daily activities (sleeping, eating, brushing teeth, reading books and so on) on a height of 1200m, while hanging on the vertical cliff. They are extreme climbers who conquered the highest and the most inaccessible peaks. For the realization of such enterprise they require significant mental and physical strength and good equipment as well.
