Human Brain

The Human brain
We are still mystified by the way our brain works. At the top of our spin, reside three pounds of tissue, controlling everything that we do. Our brain works faster than any other computer. Processing much more information, in a very small lapse of time, than any powerful machine.
We can use our brain to make time move slower? If yes, this means that we can experience one second to be one minute or even one hour. Is it possible scientifically? Normally, if we are at risk of being injured badly or our life is at risk, we have the capacity of slowing time. In emergency time, our brain works faster than usual. Our body responds to this mechanism by the release of adrenalin, and other metabolism activities like pumping of heart increases, blood vessels carry more blood to different region of our body. The effect of these metabolism in our body, make us to feel that time has been slowed down. We respond faster to outside stimuli and react accordingly with much vigour and rapidity.
Now a small fact: have you ever watch a film which is so interesting that you nearly forget to take your lunch or you miss your rendezvous with someone.
That complex machine which is our brain, had million of years of evolution,
needs energy to survive. Our brain consumes one fifth of energy we take in. In emergency cases we find our own path.

Now let’s take an example. Someone found himself alone in the middle of nowhere in an unknown ocean, after his boat has been destroyed. He is on his lifeboat with a knife only. The question is how that person will be able to survive in the middle of the sea. The brain will at first search for something eatable and drinkable by releasing the hormone ghrelin and orexin. The latter come in tiny doses but have a profound effect. These hormones make us more alert, improve our muscle efficiency. But as time pass by, that person will understand that he has to adapt to the situation. The only way he can satisfied his hunger is by fishing.

Eating the flesh of a fish. But the later does not contain all the nutrients necessary to form a balance diet. So our brain makes us turn to the eye (fresh water), spin (vitamin), liver (vitamin), skin (vitamin) and other parts until we are fully satisfied. Our body needs all these nutrients to survive. So our control center in our brain orders it to find the missing nutrients. This also shows how our ancestors survived.

Reducing food intake can make you live longer. If someone remains without food for some days, what are the consequences? In mine opinion, the following will happen:
The body will consume at first the extra fats of the body. After that, it will consume the nutrients in the muscles and bones. Thus making them become very fragile. That person will enter in a survival state until he gets the food. If not, death will follow. In the survival state, every part of our body, growth of tissue, hair, heart beat, everything, slows down. The body consumes less and less energy.
Not everyone would like to be in the survival state everyday week. So what need to be done is to eat less. Fouling our brain to consume less, can make us live longer and hence slowing down the aging process. Food intake depend upon your metabolism and how physically active you are. Your body mass also plays a big role:
Normally bigger person would require more calories than smaller ones. Also consider that the more muscle mass you have, the more calories you need to function. Someone on a 2000 calorie diet should consume fewer than 20 grams of saturated fat a day, and trans fat can and should be avoided all together. The good fats are poly- and monounsaturated fats, which you should eat about 30% of your calories in.
