Waihi Beach. It's a lovely beach, and we're right on the shore and I get a lot of pleasure out of waking up in the morning and hearing the waves roll in.

There are lots and lots of challenges that I wished - at the time - that I had done.There are lots of occasions where there were exciting things to be done but for some reason or another it was physically impossible for us to do them. I still wouldn't mind if I was able to go down into this most impressive valley in the Antarctic, but of course those things are beyond me now.

I did have my moments of despair. It was certainly not - it's not an experience I would like to have again. And then June came along.

I have a number of heroes I still have warm feelings about. [Derek] Shackleton, for instance, was definitely, and still is, one of my great heroes.

Once I've decided to do something, I do usually try to carry it through to fruition.

I always, I would say, make sure that in my presentation I'll have what I want to do. I try and make it so interesting to my companions that they want to go, too. I don't have to twist any arms or make - you know - any great challenges available.

When I was 50 years old, I actually decided to draw up a list of half a dozen things that I really hadn't done very well, and I was going to make efforts to improve. One of them was skiing, and I really did become a very much better skier.
