Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next - and disappear. That's why it's so important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.
With our blogs and tweets, digital cameras, and unlimited-gigabyte e-mail archives, participation in the online culture now means creating a trail of always present, ever searchable, unforgetting external memories that only grows as one ages.
The sport of competitive memorizing is driven by a kind of arms race where every year somebody comes up with a new way to remember more stuff more quickly, and then the rest of the field has to play catch-up.
There is a short window at the beginning of one's professional life, when it is comparatively easy to take big risks. Make the most of that time, before circumstances make you risk averse.
Truman Capote famously claimed to have nearly absolute recall of dialogue and used his prodigious memory as an excuse never to take notes or use a tape recorder, but I suspect his memory claims were just a useful cover to invent dialogue whole cloth.
Just as we accumulate memories of facts by integrating them into a network, we accumulate life experiences by integrating them into a web of other chronological memories. The denser the web, the denser the experience of time.
If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in.
Woodworking requires a completely different kind of thinking and problem-solving ability than writing. With writing, you take a set of facts and ideas, and you reason your way forward to a story that pulls them together. With woodworking, you start with an end product in mind, and reason your way backward to the raw wood.
All across Africa, the Pacific and the Americas, we find cultures that didn't know about mouth kissing until their first contact with European explorers. And the attraction was not always immediately apparent. Most considered the act of exchanging saliva revolting.
To attain the rank of grand master of memory, you must be able to perform three seemingly superhuman feats. You have to memorize 1,000 digits in under an hour, the precise order of 10 shuffled decks of playing cards in the same amount of time, and one shuffled deck in less than two minutes. There are 36 grand masters of memory in the world.
The 'OK Plateau' is that place we all get to where we just stop getting better at something. Take typing, for example. You might type and type and type all day long, but once you reach a certain level, you just don't get appreciably faster. That's because it's become automatic. You've moved it to the back of your mind's filing cabinet.
I have never been particularly good with languages. Despite a dozen years of Hebrew school and a lifetime of praying in the language, I'm ashamed to admit that I still can't read an Israeli newspaper. Besides English, the only language I speak with any degree of fluency is Spanish.
Our culture constantly inundates us with new information, and yet our brains capture so little of it. I can spend half a dozen hours reading a book and then have only a foggy notion of what it was about.
Over the last few millennia we've invented a series of technologies - from the alphabet to the scroll to the codex, the printing press, photography, the computer, the smartphone - that have made it progressively easier and easier for us to externalize our memories, for us to essentially outsource this fundamental human capacity.
Since at least the Middle Ages, philosophers and philologists have dreamed of curing natural languages of their flaws by constructing entirely new idioms according to orderly, logical principles.
One of the great challenges of our age, in which the tools of our productivity are also the tools of our leisure, is to figure out how to make more useful those moments of procrastination when we're idling in front of our computer screens.
We've forgotten how to remember, and just as importantly, we've forgotten how to pay attention. So, instead of using your smartphone to jot down crucial notes, or Googling an elusive fact, use every opportunity to practice your memory skills. Memory is a muscle, to be exercised and improved.
What distinguishes a great mnemonist, I learned, is the ability to create lavish images on the fly, to paint in the mind a scene so unlike any other it cannot be forgotten. And to do it quickly. Many competitive mnemonists argue that their skills are less a feat of memory than of creativity.
Photographic memory is often confused with another bizarre - but real - perceptual phenomenon called eidetic memory, which occurs in between 2 and 15 percent of children and very rarely in adults. An eidetic image is essentially a vivid afterimage that lingers in the mind's eye for up to a few minutes before fading away.
