I was raised by a heroic single mom, wonderful grandparents -- made incredible sacrifices for me. … But I sure wish I had had a father who was not only present, but involved. Didn't know my dad. And so my whole life, I've tried to be for Michelle and my girls what my father was not for my mother and me. … I want to be a better father, a better husband, a better man.

And I spent four years at a boarding school in the country, probably a rather abusive boarding school, and seeing very little of my parents, and that was a very bad time for me. A bad and almost a mad time. ... I think that some sort of trust, and ability for closeness, may have been compromised. And I think I’ve perhaps, to some extent, sort of kept a distance since that time, although this is not a distance I feel with my patients or my students.

Family is the center of my life. Without a doubt, the saddest day of my life was July 13, 1991, when I lost my eldest son, Harrison, in a car accident.

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.

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.

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.

What I expect to happen is that my body will fail, my mind will cease to function and that will be that. My genes will not live on, because I have had no children. I am comforted by Richard Dawkins’ theory of memes. Those are mental units: thoughts, ideas, gestures, notions, songs, beliefs, rhymes, ideals, teachings, sayings, phrases, clichés that move from mind to mind as genes move from body to body. After a lifetime of writing, teaching, broadcasting and telling too many jokes, I will leave behind more memes than many. They will all also eventually die, but so it goes.

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.

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.
