Run a few steps to be active and wise (and perhaps live long)

Although an apple a day keeps a man healthy and hearty, there is no substitute to exercise, no matter how moderate it could be. We all run to lose weight and be slim and smart. But new researches show that exercise besides helping in delaying early aging, are also helpful in making some cells in the brains more active and productive that leads to improved learning.

To start with, the exercise stimulates levels of certain brain chemicals that reverse the effects of stress. Now when the stress is removed or reduced, it makes you lively and energetic and of course less depressive. And thus an active stress free body is all geared up for more wisely things, as the specific brain chemicals called the growth factor are increased that stimulate production of new cells in the brain. The stimulated growth factors thus aid in learning and keeping the memory intact, especially in the old age.

The other day I heard of the term BMP or the bone-morphogenetic protein. Doctors and researchers are of the opinion that BMP is the stumbling block inside the brain and inhibits production of new cells that in fact defeat aging. People who are even moderately active and do some sort of exercise even for thirty minutes would in fact be defeating the BMP and helping the brain to be productive and active. How it is done is very complicated but in summary the exercise boosts levels of a brain protein called Noggin that counters the effects of BMP. Once MBP is defeated, the production of neurons, the wise cells, is given a boost and helps improve memory and learning.

These days when most of the young men are glued to their laptops throughout day and night, they are in fact slowing their learning process everyday that goes by due to lack of physical activity. Although for the time being they have their brains fully charged due to their younger age, but they need to keep a reserve for the days to come as well. Even otherwise, the physical activity provides the much needed stimulant for strained hard work and excessive use of the brain cells while sifting information from millions of posts uploaded every hour. This can only be done by a physically and mentally alert body, which is only possible if one gets out of the house for at least 30-45 minutes every day, runs around, fills in one’s lungs with fresh air rather than with the rusty air of a closed apartment. One need not be a champion of a particular sport one likes, but it should be played for keeping oneself active and healthy.

Although, exercise is also being related to defeating risks of early death, but this would remain debatable on account of spirituality as we all believe that life is a “given gift” of the Nature and cannot be lengthened or shortened. But still researchers stress that a mere 30 minutes physical activity can reduce the risk of death by 19%. However, what exercise can do is make you feel healthy, hearty and active till your last moments. And that is what matters, as being dependent in the old age at times become a nightmare, when all near and dear ones start to keep a distance.

So you’d better get into your exercise suit and go out – it won’t harm you at all (but do not eat gol gappay and then hide your stained shirt from your wife unless you buy that magical detergent too on your way back).

What did you learn today?

It was long time back that I came across a one page article in the Readers’ Digest that left a profound effect on me to learn and be a better man every day. The article was about a man who had six children and an illiterate wife. As the children were growing, the man thought their learning may depress their illiterate mother for not knowing anything. So he came up with a novel idea. One day after the dinner, he announced that from the next day onwards, after dinner, every child would tell the others a new thing that he/she learnt that day. So from then on, every night, each child would come up with a new word, a new technology news or anything and shared with the rest. So in the process, not only all the children learnt a new thing, the man himself learnt something new (if he hadn’t known it before) and also did his illiterate wife. So without making it a formal education for his wife, a forum was made where she also started learning and became wiser. It was long after the death of her husband, did the children confide with their mother the real philosophy behind their daily exercise of learning a new thing.

I learnt two things from that article, One: Do not keep a new thing that I learn to be kept to myself - it should be shared so that others know it. Two: If you think someone is ignorant or illiterate, make a novel effort to make him/her learn or understand what he/she doesn’t know. If we keep doing this, not only our own learning will improve (for trying to find out new things) but also our sharing of knowledge gets an audience and in the end helping in spreading the knowledge to those who cannot read or have no access to books or libraries.

Try it – it will be both fun and soul satisfying.

Knowledge Archives

For news, analysis, and opinion on science and technology issues, SciTech Daily (http://www.scitechdaily.com/) is a very helpful starting place. Updated 6 days a week, it keeps around 60 items on its home page before scrolling them off the bottom. The page is arranged in three columns: "Features and Background", "Books and Media", and "Analysis and Opinion". In addition, they have a link to an archive of each column.

The format for their items is a short and brisk – usually one or two sentences picked up from the story -- and a link pointing directly to the original source. Site search feature is also there. Though lack in aesthetics (it looks old fashioned), this site does not waste time. In addition to the meat of their content, they have handy link columns pointing to: "Breaking News", "Sci/Tech Publications", "Useful Media", and "Interesting Sites". They keep these lists small – some 20 to 30 links -- and the quality high. You can subscribe to an alert that brings the updates of your interests direct in your inbox.

Sister site, Arts & Letters Daily (http://www.artsandlettersdaily.com/) is also a fascinating clearinghouse of links to some of the best articles on the Web, with a strong bias toward the humanities. This too is updated six times a week in three main categories --Articles of Note, New Books, and Essays and Opinion -- the site is a good collection of great reads across an impressive range of subjects and points of view.

The content makes both SciTech Daily and Arts & Letters Daily unique in the history of knowledge that only the Web could have spawned - economical, fast, smart and full of surprises. Thought these are only a compilation and achieving but after first few online visits, one realizes that putting them together involves imagination, energy, critical judgment and intense curiosity. Visit both the sites and find subject of interest there. {By S A J Shirazi via Logic is Variable}

So from then on, every night, each child would come up with a new word, new technology news or where the Devil’s Tower was (by clicking on the link, you will learn a new thing if you hadn't known it before). So in the process not only all the children added one new thing to their vocabulary, the man himself learnt something new (if he hadn’t known it before) and so did his illiterate wife (and so did you perhaps by knowing today where the Devil’s Tower is, if you hadn’t known it before). Thus without making it a formal education for his wife, a he created a forum of learning for his wife. It was long after the death of her husband, did the children confide with her the real philosophy behind their daily exercise of learning a new thing.
