At nearly 80, with a scattering of medical and surgical problems, none disabling, I feel glad to be alive — “I’m glad I’m not dead!” sometimes bursts out of me when the weather is perfect. (This is in contrast to a story I heard from a friend who, walking with Samuel Beckett in Paris on a perfect spring morning, said to him, “Doesn’t a day like this make you glad to be alive?” to which Beckett answered, “I wouldn’t go as far as that.”) I am grateful that I have experienced many things — some wonderful, some horrible — and that I have been able to write a dozen books, to receive innumerable letters from friends, colleagues and readers, and to enjoy what Nathaniel Hawthorne called “an intercourse with the world.”

I am sorry I have wasted (and still waste) so much time; I am sorry to be as agonizingly shy at 80 as I was at 20; I am sorry that I speak no languages but my mother tongue and that I have not traveled or experienced other cultures as widely as I should have done.

I feel I should be trying to complete my life, whatever “completing a life” means. Some of my patients in their 90s or 100s say nunc dimittis — “I have had a full life, and now I am ready to go.” For some of them, this means going to heaven — it is always heaven rather than hell, though Samuel Johnson and James Boswell both quaked at the thought of going to hell and got furious with David Hume, who entertained no such beliefs. I have no belief in (or desire for) any post-mortem existence, other than in the memories of friends and the hope that some of my books may still “speak” to people after my death.

W. H. Auden often told me he thought he would live to 80 and then “bugger off” (he lived only to 67). Though it is 40 years since his death, I often dream of him, and of my parents and of former patients — all long gone but loved and important in my life.

At 80, the specter of dementia or stroke looms. A third of one’s contemporaries are dead, and many more, with profound mental or physical damage, are trapped in a tragic and minimal existence. At 80 the marks of decay are all too visible. One’s reactions are a little slower, names more frequently elude one, and one’s energies must be husbanded, but even so, one may often feel full of energy and life and not at all “old.” Perhaps, with luck, I will make it, more or less intact, for another few years and be granted the liberty to continue to love and work, the two most important things, Freud insisted, in life.
