Gerontology - the quest for longevity

The problem of extending human life, of the distance of old age and prolongation of youth is the problem indeed and very old and eternally young. People always wanted to have a long and healthy life; the lengthening of life care and health protection - two sides of a single phenomenon. Being very old, the problem is always young, for it is not solved now. However, the struggle to longevity has already begun. Formed gain momentum one of the youngest in medicine Sciences - gerontology. The name had grown all from the same seed Greek language and comes from the word "gerontas" - old. Young science about old age brought together thousands of scientists. When I got in the summer of 1972 to participate in the 9th world Congress of gerontology in Kiev there has arrived more than 3,000 experts from 43 countries. Since then the front line of research has expanded considerably. What this army of specialists knows today about the aging of the enemy with which she fights?

Why nature has not given immortality?

First of all, we do know that aging and death is the destiny of all life, without a single exception. No animal or plant organism, which has shied away from this law. Sometimes speak of the immortality of the fissiparous unicellular organisms. In reality, however, the division of microbial cells is the death of the parent body, in the depths of which are ripe two child. They grow on the ruins of the mother cell. Cell-mother dies, but no corpse, not so tragically die complex organisms.
That aging is a universal law that forces scientists to think seriously. Fight two points of view. Some experts believe that because aging is a universal pattern, it is not accidental, but is a useful property.
Living nature was gradually vyrabotala it in the course of millions of years of evolution to organisms, handed the baton of life descendants would leave the arena of the struggle for existence and not impeded these descendants to live. Other scientists believe that it is not so that ageing is one of the imperfections of nature.
Interestingly, these two interpretations were not born today. They came to us from the depth of centuries. Almost a thousand years ago lived a famous thinker and poet Omar Khayyam. Now he is known to us only as fun poet, glorifying the joy of life. In fact, it was one of the greatest minds of his age, the true encyclopaedist, which is only available from the basic science and the philosophy of time had fun writing his quatrain, Rubaie. It just so happened that often hobby is very important and glorifies man more than his seemingly main occupation. Omar Khayyam in their Rubaie sometimes expresses very deep thoughts. One of the quatrains is:
"Why is the omnipotent Creator of our bodies
to give us the immortality would not?
If we are perfect - why die?
If not perfect, then who is brakodel?
"
It is easy to see here the same contrast between these two points of view. Completely or imperfect that we are mortal? If this perfection, then what is it for? If this imperfection, as the nature of it made?.
Personally, I think that a compromise is possible between expressed interpretations. Hardly nature has shaped the ability to grow old and die during the evolution of new living creatures would spoil their body. On the other hand, in nature, as if there was no reason to correct this defect. The body that submitted the baton of life descendants, nature is no longer interested, it is all the same, what will happen to him. Nature is very efficient and does what it really needs to save the species. To cancel the old age and death for it was not required. So nature and is not taught by living organisms to be immortal.
