And in the end they robbed us, but they did let us go. But I think that that was a very useful lesson early in my journalism career, that things can go very badly wrong. At one moment you can be going down a road and things are perfect, and the next moment you’ve got some drunk soldiers who just may kill you. That fear that I felt when they were holding us for maybe 45 minutes or so in the jungle, that has never entirely left me.

One thing, it's too big a subject and I want to talk about it on paper if I talk about it at all. But I can say this much, because I thought the life that my father and mother would have had together was cut short and something of what they might have achieved I hope that I'm achieving in my work.

To so many people, I am no longer just myself. I am a reminder of a thought that is difficult for the rational brain to accept: that the elements that constitute our bodies might fail at any moment. When I originally got my diagnosis at age 35, all I could think to say was, “But I have a son.” It was the best argument I had. I can’t end. This world can’t end. It had just begun. A tragedy is like a fault line. A life is split into a before and an after, and most of the time, the before was better.

I moved to Argentina, then back to Tokyo and then to Anchorage, in Alaska, where I ran a restaurant. After 50 days the restaurant burnt down – an electrical fire. I lost my dream. I lost my money. I lost my passion. I thought about suicide, but thinking of my family and my kids made me realise I had to wake up.

I would advise them to aim high. To set their sights at a pretty tough target and don’t be too worried if you’re not successful at first. Just keep persisting and keep improving your standards, getting better and better and ultimately, you’ve got a pretty fair chance at achieving your desired goal. ... But, I do think that virtually everybody that’s born has the ability to be very competent at doing something. I think that, in itself, is worthy of aiming towards, just to be competent at doing anything you particularly wish to do.

I think it was a combination of feeling and judgment. I happened to be that sort of person that enjoyed making out plans, but I also enjoy changing plans. On an expedition, although I may start out with a detailed plan, I’m prepared to change it at any moment and completely redo it. So our expeditions turned out to be very adaptable ones. We achieved the final objectives just the same as many other expeditions, but maybe we had more fun in the process because it seemed something we could vary. We still carried on to achieve our major objectives.

In the first 33 years of my life which is up until I climbed Everest, I was a very restless and slightly unhappy sort of person. I really didn’t have a great deal of social life, but I’d become very interested in adventurous activities. Perhaps, I was, in some respects something of a loner. But after I got married, that certainly changed my life very considerably, indeed. I found that it was possible to mix having a family with continuing on with adventurous activities, but I think a great deal of that was having a suitable wife. My wife was very, long-suffering. She knew that there were certain things I wanted to do and she was happy that I should do them. She was prepared to put up with considerable periods of being alone with the kids. She, was marvelous, so it made it possible for me to do the things that I wanted to do as well.

I still regard adventure pretty much as a hobby to tell you the honest truth, and I think this approach to it keeps one refreshed almost. I think if you just regard adventure as a business, working becomes very boring as many other businesses can become. But even though adventure changed my life considerably, both in what I was doing and even economically, I’ve always regarded myself in a sense as a competent amateur.

As I’ve gotten older, my goals have become more solidified. My main concentration is on the welfare of the people I’ve worked with in the Himalayas and on human welfare in general. I’m also extremely interested in the environment and trying to encourage people to be more concerned about what we’re doing to our world. Now I’m just one of thousands and thousands of people who have these same views these days. I think this is one of the great steps forward we’ve seen in modern decades — the considerable growing interest that people have in the environment and in keeping it reasonably clean and wholesome. I certainly hope it remains that way.

I personally wouldn’t be, if I could possibly help it, involved in a serious pursuit in which there weren’t a few people who could laugh a bit about it. Because I can remember many occasions — maybe we’ve been stuck in a tent or we’re up on the side of a mountain, this heavy snow, avalanches all around us, and we can’t get up and we can’t get down, but we just sat in the tent and reminisced about occasions and days gone by and laughed about old jokes and all the rest of it. Then you really have a very good time, even though you’re sort of poised there between disaster both up and down. People who can make you laugh under those circumstances are very valuable indeed in an expedition.
