WHEN the news broke recently that a team of Belgian scientists had “discovered” a new body part — a ligament located just outside the knee — the first place my mind went was to Padua.

Padua is the small city in northern Italy where the 16th-century Brussels-born scientist Andreas Vesalius taught anatomy and created his history-making masterpiece, “De Humani Corporis Fabrica” (“On the Fabric of the Human Body”), published in 1543. The old man would have been delighted by the news, I couldn’t help thinking.

Vesalius’s wasn’t the first book on anatomy, but it was the first detailed study based entirely on actual dissection of human cadavers — on scientific fact, not supposition. It systematically dismantled the error-filled doctrine of Galenism, which rested in part on animal rather than human anatomy and had held sway for 14 centuries. But in mapping the inner body, Vesalius didn’t get everything right.

SOMEONE asked me the other day how I had gotten over the sudden death of someone I loved. What I wanted to say but found myself unable to explain (for it would have sounded too strange) was that I learned a good deal about moving through grief from some trees I once knew. They were not my trees. I didn’t plant them. I lived in an apartment surrounded by them. The only tending done was to give them my full attention over the course of four seasons.

When I moved in it was April, still cold, and the branches were bare. Facing northeast, my view of Manhattan was unobstructed, seen through a latticework veil. There were five trees, each distinct. They were not beautiful. My next-door neighbor, a landscape designer, told me that the species, Ailanthus altissima, is an urban weed. But I never expected beauty. That they were tall and strong and present was enough. I found that Ailanthus derives from an Indonesian word meaning “tree of heaven.”

Middle age arrives not with a birthday, with 48 candles on an angel food cake, but with a sudden unbidden insight in the middle of a sleepless night. You roll over and eye the clock and see all at once that the phrase “anything is possible” is not true. That is, it is no longer true for you, if it ever was. You are not going to become a doctor, or run a marathon or have a baby or sail around the world on a solo voyage documented by National Geographic. You simply haven’t the time, the feet, the eggs, or possibly even the desire required to mount such elaborate dream sequences.

In a way, this comes as a relief. When possibilities stop being endless, you can narrow the choices. Indeed, you can make hard choices, without resorting to dreams, without relying on maps, without abandoning duty. Is that not what wisdom is? Knowing when to unload what one will not need or use before approaching the next bridge.

From De arte gymnastica, 1569

IF only I had read Plato.

That’s what I thought when I saw my MRI: 28 images, impossible to deny, of a torn rotator cuff muscle — a consequence of years of weightlifting. And that’s just my shoulder. May I present C4, C5 and C6 (my herniated discs), my plantar fasciitis, my patellar tendinitis — residual damage done to a body, now 51, in the name of exercise, in pursuit of being buff.

Plato could have warned me. In “The Republic,” he advises “temperance” in physical training, likening it to learning music and poetry. Keep it “simple and flexible,” as in all things, don’t overdo. Follow this course, and you will remain “independent of medicine in all but extreme cases.”

Plato was an athlete, particularly skilled as a wrestler. His given name was Aristocles, after his grandfather, but the coach under whom he trained is said to have called him “Plato” — from the Greek for broad, platon, on account of his broad-shouldered frame. It stuck.

It is difficult now to call up the particular mood that prevailed in the AIDS epidemic’s early years. I am not talking about the first rumblings, when no one knew enough to be afraid, but further in. In those post-AZT, pre-ARV-drug days, there was very little one could do if infected. Primitive prophylaxes against certain diseases offered one’s best bet but certainly no guarantee that one wouldn’t die of Kaposi’s sarcoma or cytomegalovirus or pneumocystis carinii pneumonia. The idea of life without AIDS, much less of being alive in thirty years, was almost unimaginable. Which is why in the late eighties, coworkers and I at the San Francisco AIDS Foundation came up with an idea to get people—gay men, in particular—thinking about the future. We decided to create a time capsule. But it would not contain kitschy souvenirs—gadgets and record albums and the like. Instead, the AIDS Time Capsule would house answers to a simple question:

What message would you send to people 50 years from now about your experiences during the epidemic?

I moved to New York a year ago and felt at once at home. In the haggard buildings and bloodshot skies, in trains that never stopped running, like my racing mind at night, I recognized my insomniac self. If New York were a patient, it would be diagnosed withagrypnia excitata, a rare genetic condition characterized by insomnia, nervous energy, constant twitching, and dream enactment. An apt description of a city that never sleeps, a place where one comes to reinvent himself.

I brought very little with me, in part because I wished to leave behind reminders of the life I’d had, but also for more practical reasons. My new home was a virtual treehouse, a tiny top-floor walk-up apartment at eye-level with the Ailanthus boughs. There was not room for more than a desk, a chair, a mattress. Nor, a need: You see, the place came furnished with spectacular views of Manhattan.

What I didn’t know when I rented the place was that the French restaurant located straight below my apartment had outdoor seating till 2 a.m. Lying awake in bed, I could literally hear glasses clinking, toasts being made, six stories down. This was irritating at first. But it wasn’t long before I discovered a phenomenon heretofore unknown to me: Laughter rises. Hearing happy laughing people is no cure for insomnia but has an ameliorative effect on broken-heartedness.

I used to think that the only thing worse than having insomnia is having insomnia next to someone who falls fast asleep and stays soundlessly so till morning.

That was my life for 16 years. I lived with a man who slept, yes, like a baby. There were nights, many nights, when I literally wanted to steal his sleep — slip beneath his eyelids and yank it out of him; a kind of middle-of-the-night “Chien Andalou” moment, minus the surrealism. Instead, I spent the equivalent of at least a tenth of our relationship lying awake or reading in bed. In the end, that I happened to be deep asleep when he first went into cardiac arrest next to me now seems beyond irony. If I had not taken half a sleeping pill that night four years ago, might I have been awake and saved him?
