Ed tightened his lips and shook his head. His response was surprisingly stern. "No, Josh. You're not."

"Please, Ed, isn't there something you can do?" I pleaded.

"I'm afraid friendship is getting in the way of KL7 business. If you want to become a member of our club, you're going to have to start over." He beckoned for the waitress. "Believe me, it's much more impressive to get in to the KL7 the farther along into the evening you go."

A new table of forty-nine digits was drawn up, and two more pints were poured. This time, miraculously, my images were as clear as any I'd created all weekend-and twice as obscene. And unlike my first goround, I even had enough spare time to take one extra walk through my palace. When Ed called time, I closed my eyes and read off the forty-nine digits as confidently as if I'd been practicing them all day.

Ed stood up and gave me a high five and a hug. But Gunther, who was by now, like me, quite drunk, was not appeased. He insisted on one last hurdle before I could be officially inducted into the KL7. "You must still kiss three times the knee of a strange woman," he said.

"One knee? Three times? Now you're just making the rules up as we go," I protested.

"This is how it is," he said.

He took me by the arm and pulled me into an adjoining room of the bar, where he tried to explain the situation to a pair of middle-aged Irish women who were quietly enjoying gla.s.ses of wine. I seem to remember telling one of them not to worry, that there was nothing at all weird about the situation: We were memory champions, and this was actually quite an honor for her knee. I also seem to recall that line of logic not working, but Gunther coming up with something even more persuasive. Somehow I ended up on one knee giving three pecks to some poor woman's bare kneecap, after which Gunther hoisted my arm into the air and declared that I had met every challenge, pa.s.sed every test, and deserved admission to the world's most esteemed organization of mental athletes. "Welcome to our great club KL7!" he shouted.

My memories of the rest of that evening are splotchy. I remember sitting with Tony Buzan on a couch and repeatedly telling him that he was "the Man," while ostentatiously winking at Ed over his shoulder. I remember Ben joking that the waitress must have thought we were all a bunch of weirdos. I remember Ed telling me that "our friendship is epic."

Looking back at my reporter's notebook from that night, the gradual diminishment of my mental state is obvious. Over the course of the evening my handwriting starts to scrawl across the page. It is barely legible today, though one page is clear enough: "Holy c.r.a.p! I'm in the KL7! And I think I'm in the Women's Bathroom!"

On the facing page of my notebook, the handwriting all of a sudden becomes clean again, and transitions into the third person. I had become too inebriated to write, and was having too much fun in any case. I handed off my notebook to the nearest sober person I could find, and told her to try to be objective. There was no point pretending I was still a journalist.

Having spent the better part of a year trying to improve my memory, I returned to Florida State University to spend another day and a half being retested by Anders Ericsson and his grad students Tres and Katy in the same cramped office where almost a year earlier I had undergone a top-to-bottom examination of my memory. With Tres once again looking over my shoulder, and a head-mounted microphone once again dangling before my mouth, I retook the same battery of tests, as well as a handful of new ones. of a year trying to improve my memory, I returned to Florida State University to spend another day and a half being retested by Anders Ericsson and his grad students Tres and Katy in the same cramped office where almost a year earlier I had undergone a top-to-bottom examination of my memory. With Tres once again looking over my shoulder, and a head-mounted microphone once again dangling before my mouth, I retook the same battery of tests, as well as a handful of new ones.

So had I improved my memory? By every objective measure, I had improved something. My digit span, the gold standard by which working memory is measured, had doubled from nine to eighteen. Compared with my tests almost a year earlier, I could recall more lines of poetry, more people's names, more pieces of random information thrown my way. And yet a few nights after the world championship, I went out to dinner with a couple of friends, took the subway home, and only remembered as I was walking in the door to my parents' house that I'd driven a car to dinner. I hadn't just forgotten where I parked it. I'd forgotten I had it.

That was the paradox: For all of the memory stunts I could now perform, I was still stuck with the same old shoddy memory that misplaced car keys and cars. Even while I had greatly expanded my powers of recall for the kinds of structured information that could be crammed into a memory palace, most of the things I wanted to remember in my everyday life were not facts or figures or poems or playing cards or binary digits. Yes, I could memorize the names of dozens of people at a c.o.c.ktail party, and that was surely useful. And you could give me a family tree of English monarchs, or the terms of the American secretaries of the interior, or the dates of every major battle in World War II, and I could learn that information relatively fast, and even hold on to it for a while. These skills would have been a G.o.dsend in high school. But life, for better or worse, only occasionally resembles high school.

While my digit span may have doubled, could it really be said that my working memory was twice as good as it had been when I started my training? I wish I could say it was. But the truth is, it wasn't. When asked to recall the order of, say, a series of random inkblots or a series of color swatches or the clearance of the doorway to my parents' cellar, I was no better than average. My working memory was still limited by the same magical number seven that constrains everyone else. Any kind of information that couldn't be neatly converted into an image and dropped into a memory palace was just as hard for me to retain as it had always been. I'd upgraded my memory's software, but my hardware seemed to have remained fundamentally unchanged.

And yet clearly I had changed. Or at least how I thought about myself had changed. The most important lesson I took away from my year on the compet.i.tive memory circuit was not the secret to learning poetry by heart, but rather something far more global and, in a way, far more likely to be of service in my life. My experience had validated the old saw that practice makes perfect. But only if it's the right kind of concentrated, self-conscious, deliberate practice. I'd learned firsthand that with focus, motivation, and, above all, time, the mind can be trained to do extraordinary things. This was a tremendously empowering discovery. It made me ask myself: What else was I capable of doing, if only I used the right approach?

Once our testing had wrapped up, I asked Ericsson whether he thought anyone who'd put in the same amount of time as I did could have improved his memory to the degree that I had.

"I think that with only one data point, we don't know," he told me. "But it's rare for someone to make the kind of commitment you made, and I think your willingness to take on the challenge may make you different. You're clearly not a random person, but on the other hand, I'm not sure there's anything in how you improved that is completely outside the range of what a motivated college student could do."

When I started on this journey, standing with my journalist's notebook in the back of the Con Edison auditorium more than a year earlier, I didn't know where it would lead, how how thoroughly it would take over my life, or how it would eventually alter me. But after having learned how to memorize poetry and numbers, cards and biographies, I'm convinced that remembering more is only the most obvious benefit of the many months I spent training my memory. What I had really trained my brain to do, as much as to memorize, was to be more mindful, and to pay attention to the world around me. Remembering can only happen if you decide to take notice. thoroughly it would take over my life, or how it would eventually alter me.

What I had really trained my brain to do, as much as to memorize, was to be more mindful, and to pay attention to the world around me. Remembering can only happen if you decide to take notice.

The problem that bedeviled the synesthete S and the fictional Funes was an inability to distinguish between those details that were worth paying attention to and those that weren't. Their compulsive remembering was clearly pathological, but I can't help but imagine that their experience of the world was also, perversely, richer. n.o.body would want to have their attention captured by every triviality, but there is something to be said for the value of not merely pa.s.sing through the world, but also making some effort to capture it-if only because in trying to capture it, one gets in the habit of noticing, and appreciating.

I confess that I never got good enough at filling memory palaces on the fly to feel comfortable throwing out my Dictaphone and notebook. And as someone whose job requires knowing a little bit about a lot, my reading habits are necessarily too extensive to be able to practice more than the occasional intensive reading and memorizing that Ed preaches. Though I committed quite a few poems to heart using memory techniques, I still haven't tackled a work of literature longer than "The Love Song of J. Alfred Prufrock." Even once I'd reached the point where I could squirrel away more than thirty digits a minute in memory palaces, I still only sporadically used the techniques to memorize the phone numbers of people I actually wanted to call. I found it was just too simple to punch them into my cell phone. Occasionally, I'd memorize shopping lists, directions, or to-do lists, but only in the rare circ.u.mstances when there wasn't a pen available to jot them down. It's not that the techniques didn't work. I am walking proof that they do. It's that it is so hard to find occasion to use them in the real world in which paper, computers, cell phones, and Post-its can handle the task of remembering for me.

So why bother investing in one's memory in an age of externalized memories? The best answer I can give is the one that I received unwittingly from EP, whose memory had been so completely lost that he could not place himself in time or s.p.a.ce, or relative to other people. That is: How we perceive the world and how we act in it are products of how and what we remember. We're all just a bundle of habits shaped by our memories. And to the extent that we control our lives, we do so by gradually altering those habits, which is to say the networks of our memory. No lasting joke, invention, insight, or work of art was ever produced by an external memory. Not yet, at least. Our ability to find humor in the world, to make connections between previously unconnected notions, to create new ideas, to share in a common culture: All these essentially human acts depend on memory. Now more than ever, as the role of memory in our culture erodes at a faster pace than ever before, we need to cultivate our ability to remember. Our memories make us who we are. They are the seat of our values and source of our character. Competing to see who can memorize more pages of poetry might seem beside the point, but it's about taking a stand against forgetfulness, and embracing primal capacities from which too many of us have become estranged. That's what Ed had been trying to impart to me from the beginning: that memory training is not just for the sake of performing party tricks; it's about nurturing something profoundly and essentially human.

Before the KL7 festivities degraded into a debauched free-for-all of blindfolded chess games and drunken recitations of the previous day's poem, Gunther cornered me on a couch and asked if I would continue competing on the memory circuit. I told him that a not small part of me wanted to keep it up. It was, after all, not only strangely thrilling in a way I could have never predicted, but also addictive. That night, I could envision something I'd never before contemplated: the possibility of getting sucked in even deeper. After all, I had a U.S. t.i.tle and a speed cards record to defend, and I was sure I could break the minute barrier in cards if I only put in a bit more time. Not to mention historic dates: I could do so much better in historic dates! And there was the grand master standard I'd just missed. " 'Grand Master of Memory' would look awfully nice on a business card," I joked to Gunther (it actually is on his business card). I could have filled a memory palace with the scenes I was imagining: the millennium system I'd develop, the horse blinders I'd buy, the hours of practice I'd invest, the jet-setting to national championships around the world. But even then, at the very moment I was being offered admission to the memory circuit's sanctum sanctorum, I was sober enough to recognize that it was time for me to hang up my cleats. My experiment was over. The results were in. I told Gunther that I would miss it, but I didn't see myself coming back next year. degraded into a debauched free-for-all of blindfolded chess games and drunken recitations of the previous day's poem, Gunther cornered me on a couch and asked if I would continue competing on the memory circuit.

"It's too bad," he said, "but I understand it. It would mean a lot more practice, and that's time which you very likely can invest in a much better way." He was right, I thought. I wondered why he'd never managed to have that realization about himself.

Ed got up off the couch and raised a toast to me, his star pupil. "Let's go get a bagel," he said, and we walked out the door. I have no memory of the rest of the night. I woke up the next afternoon with a large red circle on my cheek-the imprint of my names-and-faces bronze medal. I'd forgotten to take it off.

ACKNOWLEDGMENTS.

This book took a while. I'm grateful to everyone who supported me in its creation as readers of drafts, sources of expertise, proofreaders, and friends. There are more of you than I could possibly name. I am especially grateful to all of the mental athletes who spent so much time with me, generously sharing their knowledge and their lives.

This book benefited from two editors. Vanessa Mobley guided it through its initial stages. Eamon Dolan expertly saw it through to completion. I am grateful to Ann G.o.doff for her faith in me and to everyone at Penguin Press for their work on this book's behalf. My literary agent, Elyse Cheney, is the best partner anyone could ask for. Lindsay Crouse was an extraordinary checker of hard-to-pin-down facts. Brendan Vaughan helped make my writing much sharper.

In the interests of explanatory expediency, I have moved some details, conversations, and scenes around chronologically, but these changes don't materially affect the truth of this book. To the extent that memory records and other time-sensitive facts are not always up-to-date, that is because I have tried to tell this story from the perspective I had when originally experiencing it. In the three years it took me to write this book, much changed in the world. My girlfriend became my wife. The thirty-second barrier in speed cards fell, and fell again. The poem event was finally nixed from international compet.i.tion. And sadly, EP and Kim Peek pa.s.sed away. I feel profoundly lucky for the time I was able to spend with them.

That the story of Simonides, a fifth-century-B.C. Greek, would have its first written record in a book written four centuries afterward by a Roman reflects the fact that no memory treatises have survived from ancient Greece-though some must certainly have been written. Since Cicero's recounting of the incident was written so much later than Simonides supposedly remembered the locations of the mangled bodies, n.o.body can say just how much of the story is myth. I'm willing to wager that quite a lot of it is mythical, but a marble tablet dating to 264 B.C.-two centuries before Cicero, but still two centuries after the fact-and unearthed in the seventeenth century describes Simonides as "the inventor of the system of memory aids." Still, it's hard to believe that a technique like the art of memory was invented by one person at one moment in time, in so perfectly poetic a manner. For all we know, Simonides was merely the art of memory's codifier, or maybe just a particularly adept pract.i.tioner who got tagged as its inventor. In any case, Simonides was a real person, and a real poet-the first apparently to charge for his poems and also the first to have called poetry "vocal painting" and painting "silent poetry." This is a particularly noteworthy turn of phrase for Simonides to have coined because the art of memory that he is credited with inventing is all about turning words into paintings in the mind.

The cup is a mnemonic to remind us of the poison, the tablets are a reminder of the will, and the ram's t.e.s.t.i.c.l.es are a double entendre, reminding us of the witnesses with a verbal pun on testes testes (testimony) and-since Roman purses were often made out of the s.c.r.o.t.u.m of a ram-of the possibility of bribing them.

125 Professional memorizers: Professional memorizers: My favorite story about professional memorizers is told by Seneca the Younger about a wealthy Roman aristocrat named Calvisius Sabinus, who gave up on trying to learn the great works by heart and instead hired a coterie of slaves to do it for him. My favorite story about professional memorizers is told by Seneca the Younger about a wealthy Roman aristocrat named Calvisius Sabinus, who gave up on trying to learn the great works by heart and instead hired a coterie of slaves to do it for him.

I never saw a man whose good fortune was a greater offence against propriety. His memory was so faulty that he would sometimes forget the name of Ulysses, or Achilles, or Priam . . . But nonetheless did he desire to appear learned. So he devised this shortcut to learning: he paid fabulous prices for slaves-one to know Homer by heart and another to know Hesiod; he also delegated a special slave to each of the nine lyric poets. You need not wonder that he paid high prices for these slaves . . . After collecting this retinue, he began to make life miserable for his guests; he would keep these fellows at the foot of his couch, and ask them from time to time for verses which he might repeat, and then frequently break down in the middle of a word ... Sabinus held to the opinion that what any member of his household knew, he himself also knew.

126 that was about as far as his inquiry into the matter went: that was about as far as his inquiry into the matter went: As it turns out, this radical argument was actually not new at all. In fact, it seems long ago to have been a widely accepted notion that was somehow forgotten. The first century A.D. Jewish historian Josephus wrote, "They say that even Homer did not leave his poetry in writing, but that it was transmitted by memory." And according to a tradition repeated by Cicero, the first official redaction of Homer was ordered by the Athenian tyrant Peisistratus in the sixth century B.C. As people's connections to oral culture grew more distant over the centuries, the idea of literature without writing became a harder and harder notion to digest, and eventually just came to seem implausible.

In the second century B.C., the h.e.l.lenistic ruler of Egypt, Ptolemy V Epiphanes, cut off papyrus exports in order to curtail the growth of a rival library at Pergamum in Asia Minor (the word "parchment"-derived from charta pergamena charta pergamena-is a tribute to Pergamum, where the material was used extensively). From then on, it became more common for books to be penned on stretched parchment or vellum (a final piece of ancient book etymology: vellum, which was often made from calfskin, shares the same root with "veal"), both of which lasted longer and were more transportable than papyrus.
