"What else can I do besides climbing?' says record-setting Nepali climber

Nepali guides are considered the backbone of the climbing industry in the Himalayas. They carry the majority of equipment and food, fix ropes and repair ladders. It can be a perilous occupation and the mountaineers are slowly being recognised in their own right. Sanu Sherpa is one of them - he is the first to summit the world's fourteen 8,000-metre mountains - twice.
