Geologists working somewhere in remote Siberia had drilled a hole some 14.4 kilometers deep when the drill-bit suddenly began to rotate wildly. The project manager was quoted as saying they decided that the center of the earth was hollow. Supposedly, the geologists measured temperatures of over 2000 degrees in the deep hole. They lowered super sensitive microphones to the bottom of the well, and to their horror they heard the sounds of thousands, perhaps millions, of suffering souls screaming.
Summit fever is a mountaineering term which describes the dangerous state of mind experienced by some climbers while attempting to reach a mountain summit. It is a physiological phenomenon where a person disregards dangerous weather, route conditions, physical exertion or simply refuses to take them into consideration in their desperation to reach the top.
