I went through some really terrible times. I don’t know whether I should really even mention it, but you mentioned that I had to go to prison and all that stuff. I was in a state where they had me in a straitjacket at one time. Can you understand what it would feel like to be in a straitjacket? I know. I couldn’t either, but I was, and it was brought about by sort of a drug psychosis in prison. I mean I just went completely… But it was tough, it was tough. I mean at that time they put you in — there’s a place in New York they used to call the Tombs. You’ve probably heard of it. I mean it was like a living tomb, with all the people. So I was there, and the withdrawal — physical symptoms, which were unbelievable.

If you really want to make a difference, whether it’s in helping other people, or whether it’s in fighting for your country, or whether it’s in the political arena, or journalism, or physics, you’ve got to persevere. You’ve got to understand that there are going to be some enormous bumps in the road.

For me, school was probably the most traumatising and most difficult part of my life. I already was being bullied at the age of six. I think at the time, (at) that particular school, I was probably one of three kids of colour and just bigger, stronger, bullying kids were throwing me around a lot of the time.

So it affects my work in the sense that now I’ve been kidnapped twice. So now when I’m working in a place like Iraq — even if it’s northern Iraq and someone who hasn’t survived those two things would just drive on these roads and say, like, “Oh, this is great” — but of course, for me, all I see is ISIS around every corner. Or I envision the road filling up with insurgents because I’ve seen that, and I’ve been in that situation. So it affects my work in that sense, that I’m more paranoid than I ever was, certainly than I was in my 20s.

One of these days I will encounter what Henry James called on his deathbed “the distinguished thing.” I will not be conscious of the moment of passing. In this life I have already been declared dead. It wasn’t so bad. After the first ruptured artery, the doctors thought I was finished. My wife, Chaz, said she sensed that I was still alive and was communicating to her that I wasn’t finished yet. She said our hearts were beating in unison, although my heartbeat couldn’t be discovered. She told the doctors I was alive, they did what doctors do, and here I am, alive.

When I was a child the mailman came once a day. Now the mail arrives every moment. I used to believe it was preposterous that people could fall in love online. Now I see that all relationships are virtual, even those that take place in person. Whether we use our bodies or a keyboard, it all comes down to two minds crying out from their solitude.

Many readers have informed me that it is a tragic and dreary business to go into death without faith. I don’t feel that way. “Faith” is neutral. All depends on what is believed in. I have no desire to live forever. The concept frightens me. I am 69, have had cancer, will die sooner than most of those reading this. That is in the nature of things.

I know it is coming, and I do not fear it, because I believe there is nothing on the other side of death to fear. I hope to be spared as much pain as possible on the approach path. I was perfectly content before I was born, and I think of death as the same state. I am grateful for the gifts of intelligence, love, wonder and laughter. You can’t say it wasn’t interesting. My lifetime’s memories are what I have brought home from the trip. I will require them for eternity no more than that little souvenir of the Eiffel Tower I brought home from Paris.

I believe that if, at the end, according to our abilities, we have done something to make others a little happier, and something to make ourselves a little happier, that is about the best we can do. To make others less happy is a crime. To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn’t always know this and am happy I lived long enough to find it out.
