Did the Victorians fear death? As Death says in one of my own books, most men don't fear death, they fear those things – the knife, the shipwreck, the illness, the bomb – that proceed, by micro seconds if you're lucky and many years if you're not, the moment of death.

These matters have become discussable with one’s friends, not, of course, as a frequent part of gossip over lunch in the dining room (our only communal occasion) but from time to time, perhaps when admiring someone’s stoicism if their frailty is becoming painfully apparent, or feeling sad at someone else’s inability to accept what seems to be imminent. As a result of this openness, I think that most of the people here would consider it foolish to be frightened of being dead. All of us, however, feel some degree of anxiety about the process of dying.

I cannot pretend I am without fear. But my predominant feeling is one of gratitude. I have loved and been loved; I have been given much and I have given something in return; I have read and traveled and thought and written. I have had an intercourse with the world, the special intercourse of writers and readers. Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and adventure.

I’ve had a couple of ex-girlfriends sort of accuse me of having a personality disorder! … No, I don’t know. I’ve always been afraid of death. I’ve never wanted to die. Last year, I watched this guy die in Red Rock. It was this horrible freak accident thing. He fell and he cracked his head and basically just bled out. That was the first time I’d ever actually seen a climbing accident like that. It was kind of sobering — he was even wearing a helmet — it was a reminder of how dangerous climbing can be if things go wrong even when you have all the ropes on.

I was terribly upset at the time, because I felt I had betrayed [my wife] Kate and my family by being so stupid. But I’ve accepted it.

For the last few weeks, I've been completely happy. I've got my next PSA in three weeks' time. It may well show my PSA is starting to go up, and the cancer's coming back. Totally to my surprise, I've acquired this sort of Buddhist Zen outlook. Well, the future doesn't exist. I'm well. I'm happy at the moment. I've had a wonderful, exciting life. I've made lots of mistakes. I've trampled on people - yak, yak, yak, as I discuss in my books. But at the moment, today, the sun is shining. I'm very well. It's not that I'm in denial, but I think, well, all right. It may be bad news in three weeks' time, but that's three weeks away. At the moment, I'm well.

I should have known that I might not like what my brain scan showed, just as I should have known that the symptoms of prostatism that were increasingly bothering me were just as likely to be caused by cancer as by the benign prostatic enlargement that happens in most men as they age. But I continued to think that illness happened to patients and not to doctors, even though I was now retired. Twenty months after I had my brain scanned, I was diagnosed with advanced prostate cancer. I had had typical symptoms for years, steadily getting worse, but it took me a long time before I could bring myself to ask for help. I thought I was being stoical when in reality I was being a coward. I simply couldn’t believe the diagnosis at first, so deeply ingrained was my denial.

A close, loving family and work position in society which is meaningful, which is about making the world a better place rather than getting a bigger - having a bigger bank account.

Sufficiently well to see Johnson and Truss and then two or three days later, she’s dead. I thought, that’s fantastic. That’s something to celebrate. That’s a great death.

I was looking at ageing in action, in black-and-white MRI pixels, death and dissolution foretold, and already partly achieved. My 70-year-old brain was shrunken and withered, a worn and sad version of what it once must have been. There were also ominous white spots in the white matter, signs of ischaemic damage, small-vessel disease, known in the trade as white matter hyperintensities – there are various names for them. They looked like some evil pox. Not to put too fine a point on it, my brain is starting to rot. I am starting to rot. It is the writing on the wall, a deadline.
