I think global warming is a very real problem for our world. I've seen the changes that have taken place in the Antarctic, in the Himalayas, where the natural ice has sort of faded away, and there's no doubt in my mind that we're living in a strange world, a world which is not easy to understand or handle, But there's nothing you can do about, you just have to live your life as best you can.

I will come again & conquer you because as a mountain you can't grow, but as a human, I can

I think the whole attitude towards climbing Mount Everest has become rather horrifying. The people just want to get to the top. They don't give a damn for anybody else who may be in distress and it doesn't impress me at all that they leave someone lying under a rock to die.

I'm a very, very modest person and with limited abilities. I do have the wish to succeed in anything I undertake, and that does help out, but, in general, there are so many other people who are skilled in their field that I feel very ordinary.

I had never experienced anything like it before and I don't think I have experienced anything like it since [on Ruapehu]. It was my dreams coming true in a way, and from there on I tended to become more of a doer than a dreamer.

I was certainly seriously emotionally affected [ when Louise Hillary and Belinda Hillary died], but we were building the hospital at the time and I decided that the only thing to do was to carry on and complete the hospital - and it was a jolly good hospital too, I might say. So I really did it by working and working on the things that Louise and I had been working on.

I think I mainly climb mountains because I get a great deal of enjoyment out of it. I never attempt to analyze these things too thoroughly, but I think that all mountaineers do get a great deal of satisfaction out of overcoming some challenge which they think is very difficult for them, or which perhaps may be a little dangerous.
