Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it.

My relationship with the mountains actually started when I was 16. Every year, a group used to be taken from Auckland Grammar down to the Tangariro National Park for a skiing holiday.

Ever since the morning of May 29, 1953, when Tenzing Norgay and I became the first climbers to step onto the summit of Mount Everest, I've been called a great adventurer.

I have enjoyed great satisfaction from my climb of Everest and my trips to the poles. But there's no doubt that my most worthwhile things have been the building of schools and medical clinics.
