Rosset's goal was to 'relearn' the natural survival skills which many urban males seem to have forgotten.
"At the beginning I had to try hard to survive," the former professional snowboarder said.
"I had to find the food and water, build shelter, learn how to fish, everything."
Last September, just 10 days in, he had a realisation that he was all alone and would be for many months to come.
"That was very hard, without my family, my girlfriend, my friends. There was a lot of loneliness."
But he was kept busy just trying to survive.
