Has knowing that you will die changed how you live?

I just thought right away that I wanted to work. ... This is a good job. It's been a good job. Work is the most effective drug there can possibly be. ... I'm on the periphery of a lot of despair, of course. ... You'd have to be stupid not to be. I have my moments when I'm not too thrilled about this whole deal. But at the same time, the songs have never come like this, so I'd have to feel more gratitude than anything else. I'm probably in the intensest creative period of my life.

This is obviously not how I wanted things to turn out, but my wife and I have no regrets; we did everything I could to maximize my odds. And we want to thank everyone who has so graciously helped us. The really weird part of all this is that I'm not depressed. I'm not in denial (I assure you, I am fully aware of what is going to happen), nor am I whistling in the dark, but after having felt crappy and sick for 11 months, to finally be fully healthy again is so exhilarating that it's a wonderful emotional buoy. So I am going to enjoy each day very fully, and play hard with my kids until I can't.

Let us consider me as a test case. As I have said, I would like to die peacefully with Thomas Tallis on my iPod before the disease takes me over and I hope that will not be for quite some time to come, because if I knew that I could die at any time I wanted, then suddenly every day would be as precious as a million pounds. If I knew that I could die, I would live. My life, my death, my choice.

I see the future as something that could come crashing down very fast. Let me put it slightly by way of a comparison. Normal people, and I use the term very deliberately, by this not otherwise able situation - I'm disabled. I'm abnormal. Normal people dont think very much about the medium term future. They think only about the present, which is constantly changing for them or the very far future, which is just an abstraction. For me, its the other way around, my present never changes. So I dont really think about. But the medium term involves my death so I'm quite conscious of what is going to happen to me in about a year, maybe two years, who knows, whereas no one else I know thinks like that.

I live by the day. Just sitting in the park, looking at the flowers thinking how beautiful they are. It's almost … not hallucinogenic but it's a much stronger feeling than previously. For me, at the moment, going for a walk in the park with Gail is heaven.

I began to realize that coming face to face with my own mortality, in a sense, had changed both nothing and everything. Before my cancer was diagnosed, I knew that someday I would die, but I didn’t know when. After the diagnosis, I knew that someday I would die, but I didn’t know when. But now I knew it acutely. The problem wasn’t really a scientific one. The fact of death is unsettling. Yet there is no other way to live.

I feel a sudden clear focus and perspective. There is no time for anything inessential. I must focus on myself, my work and my friends. I shall no longer look at “NewsHour” every night. I shall no longer pay any attention to politics or arguments about global warming. This is not indifference but detachment — I still care deeply about the Middle East, about global warming, about growing inequality, but these are no longer my business; they belong to the future. I rejoice when I meet gifted young people — even the one who biopsied and diagnosed my metastases. I feel the future is in good hands.

Yeah. These books are all around me and they'll be here when I go and I'm that sick. I just don't know when it ends. But in 2010, I got really ill and leukaemia was one of the things I was diagnosed with and eventually it will switch me off. So it raises the question: what do you do? Do you lie down and give up? Read the Bible? Or do you go on as you were reading and writing. And I've done the second and I've just done a little bit called Latest Readings which is about the books I've been reading lately and I could do another volume of that because I'm still reading.

But in the weeks after I learned that the breast cancer I have been in treatment for over the past year had spread to my bones — breaking my spine and becoming incurable and most likely fatal — finding the perfect living-room couch has begun to feel like the most important thing I’ve ever done.

Every 90 days I lie in a whirling CT machine, dye coursing through my veins, and the doctors look to see whether the tumors in my liver are growing. If they are not, the doctors smile and schedule another scan. The rhythm has been the same since my doctors told me I had stage IV colon cancer two and a half years ago. I live for three months, take a deep breath and hope to start over again. I will probably do this for the rest of my life. Whatever that means.

what’s the difference? If I die in two years’ time, what will I do between now and then which I don’t want to do now? The main reason for living longer now is for the sake of my family and my wife. And this is not rationalist bravado entirely. I’ve had a wonderful life. Yes, I’ve done a lot of things I shouldn’t have done. But you know, I’ve had a full, complete life, and there’s nothing more I can do to complete it. Dying when you’re younger is obviously a totally different situation. Or losing a child. I mean, that’s beyond words.
