Improve your memory

 

Your ability to remember increases when you nurture your brain with a good diet and other healthy habits.  Physical exercise increases oxygen to your brain and reduces the risk for disorders that lead to memory loss, such as diabetes and cardiovascular disease. Exercise may also enhance the effects of helpful brain chemicals and protect brain cells.

When you’re sleep deprived, your brain can’t operate at full capacity. Research shows that sleep is necessary for memory consolidation, with the key memory-enhancing activity occurring during the deepest stages of sleep.

Research shows that having meaningful relationships and a strong support system are vital not only to emotional health, but also to brain health. In one recent study from the Harvard School of Public Health, for example, researchers found that people with the most active social lives had the slowest rate of memory decline.

 

Stress is one of the brain’s worst enemies. Research has found that chronic and acute stress have adverse effects on memory processing systems. Therefore, it is important to find mechanisms in which one can reduce the amount of stress in their lives when seeking to improve memory.

Research suggests that what food we eat can influence memory processing. Glucose, flavonoids, fat and calories all affect memory areas of the brain. Human and animal research using flavonoids such as grapes, tea, cocoa, blueberries, as well as ginkgo biloba extracts, have all shown beneficial effects on mental performance.

There’s evidence that light to moderate alcohol consumption can improve memory and cognition. some studies have found that moderate drinkers do better on certain tests of memory and cognition than nondrinkers and heavy drinkers, A French study that followed almost 4,000 people over the age of 65 found that light drinkers, who consumed up to two glasses of wine a day, were 45 percent less likely to develop Alzheimer's disease than nondrinkers.

Memory, like muscular strength, requires you to “use it or lose it.” The more you work out your brain, the better you’ll be able to process and remember information. Do crossword puzzles. Read a section of the newspaper that you normally skip. Learn to play a musical instrument.

Take care of your memory because it is the only thing that keeps you alive and makes you to feel alive.

How to Remember Everything?

 

Want to Remember Everything You'll Ever Learn?

Surrender to This Algorithm

The winter sun sets in mid-afternoon in Kolobrzeg, Poland, but the early twilight does not deter people from taking their regular outdoor promenade. Bundled up in parkas with fur-trimmed hoods, strolling hand in mittened hand along the edge of the Baltic Sea, off-season tourists from Germany stop openmouthed when they see a tall, well-built, nearly naked man running up and down the sand.

"Kalt? Kalt?" one of them calls out. The man gives a polite but vague answer, then turns and dives into the waves. After swimming back and forth in the 40-degree water for a few minutes, he emerges from the surf and jogs briefly along the shore. The wind is strong, but the man makes no move to get dressed. Passersby continue to comment and stare. "This is one of the reasons I prefer anonymity," he tells me in English. "You do something even slightly out of the ordinary and it causes a sensation."

Piotr Wozniak's quest for anonymity has been successful. Nobody along this string of little beach resorts recognizes him as the inventor of a technique to turn people into geniuses. A portion of this technique, embodied in a software program called SuperMemo, has enthusiastic users around the world. They apply it mainly to learning languages, and it's popular among people for whom fluency is a necessity — students from Poland or other poor countries aiming to score well enough on English-language exams to study abroad. A substantial number of them do not pay for it, and pirated copies are ubiquitous on software bulletin boards in China, where it competes with knockoffs like SugarMemo.

SuperMemo is based on the insight that there is an ideal moment to practice what you've learned. Practice too soon and you waste your time. Practice too late and you've forgotten the material and have to relearn it. The right time to practice is just at the moment you're about to forget. Unfortunately, this moment is different for every person and each bit of information. Imagine a pile of thousands of flash cards. Somewhere in this pile are the ones you should be practicing right now. Which are they?

Fortunately, human forgetting follows a pattern. We forget exponentially. A graph of our likelihood of getting the correct answer on a quiz sweeps quickly downward over time and then levels off. This pattern has long been known to cognitive psychology, but it has been difficult to put to practical use. It's too complex for us to employ with our naked brains.

Twenty years ago, Wozniak realized that computers could easily calculate the moment of forgetting if he could discover the right algorithm. SuperMemo is the result of his research. It predicts the future state of a person's memory and schedules information reviews at the optimal time. The effect is striking. Users can seal huge quantities of vocabulary into their brains. But for Wozniak, 46, helping people learn a foreign language fast is just the tiniest part of his goal. As we plan the days, weeks, even years of our lives, he would have us rely not merely on our traditional sources of self-knowledge — introspection, intuition, and conscious thought — but also on something new: predictions about ourselves encoded in machines.

Given the chance to observe our behaviors, computers can run simulations, modeling different versions of our path through the world. By tuning these models for top performance, computers will give us rules to live by. They will be able to tell us when to wake, sleep, learn, and exercise; they will cue us to remember what we've read, help us track whom we've met, and remind us of our goals. Computers, in Wozniak's scheme, will increase our intellectual capacity and enhance our rational self-control.

The reason the inventor of SuperMemo pursues extreme anonymity, asking me to conceal his exact location and shunning even casual recognition by users of his software, is not because he's paranoid or a misanthrope but because he wants to avoid random interruptions to a long-running experiment he's conducting on himself. Wozniak is a kind of algorithmic man. He's exploring what it's like to live in strict obedience to reason. On first encounter, he appears to be one of the happiest people I've ever met.
