Cave sitting

Competitive cave sitting, or cave dwelling, began in the 1950s, as a test of endurance. Early cave sits involved groups of people, but over time the endeavour became an individual pursuit. Cave sitting requires a competitor to stay in a cave for as long as possible without direct interaction with other humans or the outside world. In addition to the desire to set a new record, the purpose of competitive cave sits have included testing the effects of solitude and darkness on humans, testing possible options for protection from nuclear fallout and studying the body's circadian rhythms. Since the 1950s, cave sitting endurance records have been set in France, America, Italy, Australia, England, Serbia and Spain. In the 1960s, sections of the press described cave sitting as a sport. The world record is currently held by Serbian Milutin Veljković who sat alone in a cave for 464 days in the Svrljig Mountains in eastern Serbia in 1971.
