A death threat at Glastonbury festival in 1989. The police told me not to go on, but I said I had to because I was headlining. So I wore a bullet-proof vest. It seemed unlikely that I would be assassinated, but it was shocking and very stressful.

In 2016, I fell off stage in Switzerland and broke my back in four places.

A blood clot in my artery when I was 23.

And actually now having had the advantage of the Truth and Reconciliation Commission and being able to look at some of the records of what the apartheid government was doing, the thing that is surprising to me is why so many of us survived. I mean, how is it that they did not assassinate more of us?

Well my memory for names is absolutely appalling, but I know I did pass through a phase of books like King Solomon’s Mines. H. Rider Haggard was the author, and he wrote these great romantic adventure stories. I used to enjoy Georgette Heyer, in which the hero was usually a rather middle-aged gentleman, a very good sword fighter, with a beautiful young lady and all the rest of it. Great sword fighting and all highly romantic, adventurous activity. I used to find these things quite entertaining. I even passed through a phase when I quite enjoyed Western stories. Nowadays, I find them a little on the naive side but, for a period, I found the Western stories quite entertaining light reading. They are very romanticized, as we all know. Later on, I became much more interested in reading biographies, particularly about people who had made their mark in the community. I still enjoy reading books of that nature.

I’ve been very fortunate in that respect. In the early days I liked to be the bomb of the expedition, and rush on ahead and do things faster than anybody else. Those days merged very pleasantly into periods when I organized and inspired expeditions and selected these younger people who were then the bombs of the operation. And then it drifted into this involvement with the people of the area, still loving the mountains, but finding the people just as important too. And on and on it’s gone. As I get older and less physically capable, I find other challenges have grown up and become just as important to me.

Those years from 1953 to 1975 were extremely happy years for me. I did many adventurous activities. I got deeply involved in these aid programs for the people of the Himalayas. I had a nice family, we took our family into the out-of-doors, we camped and we swam and we clambered around the hills. For me, it was a very full and a very happy existence.

I think motivation is the single most important factor in any sort of success. Physical fitness is important, technical skill is important, and maybe even the desire for money is important in some respects. But a sort of basic motivation, the desire to succeed, to stretch yourself to the utmost is the most important factor. Certainly in the field of exploration and activity, it’s the thing that makes the difference between someone who does really well and someone who doesn’t.

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 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.
