Bouldering is a form of rock climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses.While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls.
Rock climbing can trace its origins to the late 19th-century, and has since developed into several main sub-disciplines.Single-pitch and multi-pitch (and big wall) climbing, can be performed in varying styles (including aid, sport, traditional, free solo, and top-roping), while the standalone discipline of bouldering (or boulder climbing) is by definition performed in a free solo format.

Mountain sickness may progress to HACE (high-altitude cerebral edema) and HAPE (high-altitude pulmonary edema), both of which can be fatal within 24 hours. [42] [44] [46] In high mountains, atmospheric pressure is lower and this means that less oxygen is available to breathe. [42] This is the underlying cause of altitude sickness.
Bogin points out that Kollmann had intended the meaning to be "retaining youth", but had evidently confused the Greek teínein with the Latin tenere, which had the meaning he wanted, "to retain", so that the new word would mean "the retaining of youth (into adulthood)". [15] In 1926, Louis Bolk described neoteny as the major process in ...
