How does one improve memory and concentration? : Einstein had a peculiar habit. He liked to take a nap while holding a key in his hand. How did he do it?
Like this: He would sit in a chair, with his arm hanging down, holding a key. Under his hand, he would place a metal plate.
Now, when he started to fall asleep, his hand would relax. The key would fall, making a clang against the plate. The noise would wake him up.

What’s the point? It’s a way of hacking our brain.
With Einstein’s method, we can take advantage of the hypnagogic phase without falling into a deep sleep. The result? New ideas, better concentration, sharper memory.
I’ve been trying this method for a few days now. At first, I found it strange and frustrating, but the effects have been noticeable. My productivity has increased by 30%. Ideas for writing flow more easily. Even my dreams have become more vivid and easier to remember.
The bottom line is that the power of a nap should not be underestimated. With a little Einstein-style trick, we can maximize our brain’s potential.

What is Memory?
As we age, it’s common to worry about losing our memories (That’s partly because a certain amount of age-related memory loss is perfectly normal). In order to preserve your memory as you age, it’s important to understand how memory functions. So, what is memory? Where in the brain are memories stored, and how does the brain retrieve them?
Quite simply, memory is our ability to recall information. Scientists talk about different types of memories based either on their content or on how we use the information. For example, remembering the layout of your grandmother’s kitchen is different in both content and purpose than remembering the middle three digits of a plumber’s phone number while looking at his business card as you dial the phone. The main two categories for memories are short-term and long-term.
Short-term memories involve information that you only need to recall for a few seconds or minutes. If you’re turning at an intersection, the fact that there were no cars coming when you looked to the left is important, but once you’ve made your turn you will quickly discard the information because it is no longer relevant. Keeping it around would unnecessarily clutter your brain.
Long-term memories contain the information that makes you who you are: not just facts (like the capital of Kansas) or events (like your graduation party), but skills and processes (like typing or dancing the Macarena). Long-term memory is long-lasting, but changing; a memory can develop from retelling a story or from new information learned after the event.
Memories are not stored in one place in the brain. Instead, the sensory components of memory (sight, smell, sound, etc.) are distributed across different areas of the brain, and the act of remembering occurs when the brain puts those pieces back together.
Each time a memory is formed, its components are cataloged in a deep structure in the brain called the hippocampus. Next to the hippocampus is the emotional center of the brain, the amygdala. It marks certain memories as important or emotionally powerful. The various components of memory are then distributed mostly across sections of the cerebral cortex, which is the outer layer of the brain.
Just when we’re about to fall asleep, our brain enters a phase called “hypnagogia.” During this phase, our brain becomes super creative. Crazy ideas start to come to us. But usually, we fall asleep too quickly, so we don’t remember anything.
