Nando Parrado's survival in the face of unspeakable horror has been made into a bestseller and a film. Now he tells us in his own words just what he went through.
After the plane carrying him and his fellow rugby team-mates crashed in the Andes mountains, those that survived faced certain death through starvation - unless they contemplated the unthinkable; eating the bodies of their dead friends.
After two months Nando Parrado and a friend attempted to scale the mountains surrounding them and find help. Incredibly, they achieved this and the rescue began.
Just what effect does an experience this extreme have on your life? And can it carry any lessons for others?
