Professor survives 70 foot fall in the Himalayas: I went from walking in the bright sunlight to falling down that mineshaft

Professor John All was climbing alone on a Himalayan mountain when the ground beneath his feet gave way. He fell 70 feet down an icy crevasse, and managed to stop himself from falling even further. All told Wolf how he climbed back to the surface despite not being able to rely on the right side of his body, explaining "if I stopped or rested or hesitated I would be dead." All managed to record video of the experience and even used his phone to message for help on social media. He spoke to Wolf shortly after leaving a Nepalese hospital.
