The late photographer Michel Hurst happily endured what most of us might consider suffering. In his adventurous youth, he rode a rented bicycle a thousand miles across India. For a spell, he posted up in a commune in the South of France that didn’t have electricity or running water. He once lived in a cave in the Canary Islands for four months, naked, like a hermit chasing the beatific vision. He hitchhiked across the Sahara Desert, twice.
