A skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s.

Free solo climbing, or free soloing, is a form of rock climbing where the climbers climb solo without ropes or other protective equipment, using only their climbing shoes and their climbing chalk. Free soloing is the most dangerous form of climbing, and, unlike bouldering, free soloists climb above safe heights, where a fall can be fatal. Though many climbers have free soloed climbing grades they are very comfortable on, only a tiny group free solo regularly, and at grades closer to the limit of their abilities.
