Improve Memory, Mind, Brain workout

DO you find that you aren’t as ‘on top’ of things as you used to be? Maybe you forget oft-repeated telephone numbers or misplace important documents. You blame your brain and assume that this is an inevitable result of advancing years.

Well, you couldn’t be more mistaken! Memory lapses or an overloaded brain can occur at any stage. The trick is to keep your brain alert and active. Remember, that like any other muscle in your body, your brain too, is a muscle. If you don’t use it, you are definitely going to lose it! There’s a reason experts have almost gone blue in the face emphasising the importance of mental exercises or mind games, that’ll keep your brain agile and stimulated. Agrees Dr Sujay Rao, a neurologist at Manipal Hospital, “Actively using your brain can retard certain age-related diseases. In fact, using your brain to the maximum extent means that the various connections of your brain cells are alive. Otherwise, the cells could die out. And certain board games definitely help here.”
The brain is called upon to simultaneously regulate unconscious functions like breathing, body temperature and digestion; conscious functions, such as movement and talking; and so-called cognitive functions, such as thinking, learning, feeling and remembering. To help the brain keep up this lifelong juggling act, researchers are increasingly coming to view a healthy brain as a “worked out” brain – one that is regularly stimulated and challenged by rigorous mind-taxing tasks.
Comfortably ensconced in the skull, the brain needs to be used and exercised just like any other part of our anatomy. Your brain does grow smaller with age, and if you don’t stimulate it enough, then according to experts, you actually risk lowering your capacity for learning! Research shows that keeping your brain nimble with new, challenging and stimulating activities is the best way to keep your mind sharp. That’s exactly where the importance of games and puzzles like sudoku, kakuro, nintendo, monopoly, jigsaws, etc come in. In fact, research shows that by stretching the brain with regular crossword and sudoku puzzles, you can make your brain function like it’s 14 years younger!
The thing to remember is that though lack of sleep, stress and poor eating habits can adversely affect your brain, the effects can be countered if you flex your mental muscle enough. Explains Ronald Petersen, a neurologist and specialist in memory disorders,
“Brain exercises don’t need to be the
equivalent of weight lifting.
Playing board games, reading, taking classes or
anything that engages your mind, helps.” Brain exercises are one of the few things that people can do to be proactive about stopping or slowing down cognitive decline. And it’s infinitely better than popping pills! In fact, a study conducted in China found that cognitive ability declined less in elderly people who did puzzles, played games or engaged in other mentally stimulating activities.
The brain obviously doesn’t just need a workout, it basically thrives on it. Like Dr Joe Verghese, an assistant professor of neurology at Albert Einstein College of Medicine in New
York City, says, “The more you indulge in mentally stimulating activities – such as crossword puzzles or playing chess – the better it is.” He recently co-authored a study that found that seniors who engage in a wide variety of mental pursuits while at leisure – such as playing a musical instrument, reading and playing cards or board-games – seem to dramatically lower their risk for developing dementia. But he stresses that it’s never too early to incorporate mental exercise into the daily planner. In fact, it’s a habit that should be encouraged right from childhood. “If you haven’t built a lifestyle that includes mentally stimulating activities in your 50s as a habit, it’s unlikely you will do so in your 60s,” he points out.
The Alzheimer’s Association also recommends puzzles as therapy based on studies which suggest that they might improve memory, attention and problem-solving capabilities, while staving off mental decline and perhaps, even reducing the risk of Alzheimer’s disease. Studies of patients with Alzheimer’s, dementia or attention deficit disorder have found that those who play games have better speech and brain function as well. There is growing evidence that people who engage in puzzles, board games and other mentally stimulating activities can reduce the risk of memory loss and dementia as they age.
Adds Dr Milind Vaidya, a neurosurgeon at Mumbai’s Wockhardt Hospital, “Routine activities – or daily chores – don’t really make optimum use of the brain. That’s why mental exercises are required to keep the brain fit and its cells active.”
That might explain why people these days can be seen furiously scribbling into newspapers while they frantically finish the all-important sudoku, or perhaps the cryptic crossword! Like Avani Patel, a 24-year-old sudoku enthusiast says, “As sudoku is a very logical game, I’d like to believe that at times I apply the same logic in real life too. After all, as you go about filling up each column, it does teach you that one can look at a problem in many ways. And that if you persevere hard enough, there definitely will be a solution.” No wonder the entire country is saying, Lage Raho…
According to Dr Vaidya, the more one exercises the brain – especially with numbers – the better will be one’s retention power as well as productivity. “If you notice, there are many senior citizens who have an extremely agile and alert brain. Why? Chances are that they’ve been handling or looking into the family’s finances for years, so their brains have been active. As something like sudoku is also all about numbers, it definitely goes a long way in keeping your brain fit,” he explains.
So perhaps it’s time for you to stop running away from numbers and actually befriend them as they may just be your saving grace in your golden years!
Just think about it as a mental workout – the more you do, the better

fast processing in brain

You must have heard people saying that "do not indulge in useless things". Why, let us take the example of computer. Like humans, computers also have memory to store data and processor to process the data. Now, the data which is required very frequently is stored in processor registers. Now to produce right results it is very important to have the right data(always applicable in case of computers) in memory. If wrong data or extra data keep residing in the processor memory then either the result will be wrong or delayed.
Similarly, human brain also processes the data which is available to it. Now, how the data is made available to the brain, through our memory. And, what is contained in our memory, the
thoughts generated by the activities in which we are involved. Now, if we keep ourselves involved in useless things then this data always keeps the active memory(let us call processor registers as active memory to talk about human brain) full and when we need to think on something else or something useful then it will take time to make it available to the brain as some other data is already there in active memory.
For example, if you are crossing a busy road with a contained mind then you will take more time to react against a fast coming vehicle. What can be done to avoid this, to keep the active memory free and to process the data fast. Now, after realizing the logical reason behind the processing of data in your brain and understanding how useless indulgence can be responsible for making you slow. Then, any time any place you can give a thought to know your state of mind and you will come to know that what is there in your mind, is this really useful, necessary. Slowly slowly you may start checking your memory very frequently and help yourself in keep it clean from useless data(thoughts).

mapping and associativity in brain

Have you ever tried to thought how thoughts or more precisely how data is evolved in human mind. It has been more than few years when I was trying to think hard on some topic, I was not getting anything in my mind related to that topic. But, when I remembered something then very soon I was also able to remember other details also about the same topic.
How do we put data in our mind, sequentially. One thing is to sure that to think you need something, some data to work upon. When one starts thinking about any topic then first something comes in your mind and then slowly other things also keep coming. From this new data, some is the resultant of the processing of previous data and some matching data is already found in your mind, in your memory.
Whenever someone tries to remember any past data, it seems to be stored as images, all connected and linked to each other. You remember a particular one and you find a full chain of related data. For example, if some word like, country comes to your mind then depending upon the state of your mind you start thinking in a particular direction about that country. You may start thinking about the population of that country, if so, then you may start thinking about the division of population geographically. This may trigger a thought about the terrains or mountains or rivers in that country. As thoughts are based on data so, one can go to any direction depending on the availability and associativity of data.

meaning of experience

I came across a very good example of experience that can be related to the definition of right and wrong also. I used to think that why people do their business in greedy manner. Let us take an example, whenever I saw a newspaper publishing more advertisements than the news, I used to think that how can these guys so greedy and irresponsible. People pay to read the news and these guys are selling ads, but yesterday when I was thinking about putting a web link on every outgoing mail, I started to think that I will put a very small link at some hidden sort of place on the mail. But, I did not stop there and I kept thinking about covering more and more space in a greedy manner.
Then, suddenly I found myself justifying the ideas of covering more and more space and thought that what is wrong in utilizing the space which is available. But, when others were doing this then I was reacting in a different way. What does it mean? it means that mere reading or seeing anything does not create a real experience, only when one feels with his/her own senses then it becomes a real experience.
Without this experience I would keep thinking that some people are always greedy and do the business in greedy manner. But now, I probably understand that some feelings, some patterns evolve slowly and every small feeling(greed) becomes a base for a bigger feeling(greed). But, when a person does not have the experience of a feeling at the beginning level(putting just a web link) then after experiencing the feeling at bigger level(news paper greeds), he/she may start calling people wrong. As my greed also has stages, started from a very small level i.e putting a web link and subsequently increased to cover the whole page.

Whether greedy business is right or wrong is a different matter but the exercise shows that how perspectives are created in human mind and how experiences influence the perspectives .

A surprising decision

Today, I came across one more behavior of mind.
My friend asked me a question and i had two options to answer, i.e, first was yes and second was no, nut I was not sure which one to say. Next moment I found myself saying 'I dont know' and later on I realized that this was a more correct answer . Mind did not choose either of the options? b'coz I was not sure? or in the end it was so fast to decide that I even could not realize that the decision has been changed.

Was it because I was really trying to get a non-biased answer? what if by nature I was a dis-honest person who only wants to say the things which are socially favorable to him.
