EUTOPIA
THIS EXPLORER DISCOVERED HUMAN TIME WARP BY LIVING IN A CAVE




On July 16, 1962, French geologist Michel Siffre entered a darkened cave, where he planned to remain for two months. Tracking the days according to his sleep patterns (one night’s sleep equals one day), he believed his underground stay was ending on Aug. 20. Instead, when he emerged, it was Sept. 14 — 25 days later.
