Since time immemorial, people dream about the possibility of preserving youth. What is a man that runs a youth? Grow old and die? No, life extension is currently the minds of scientists and duration of human life in modern conditions is the most important concern of the society. However, the problem is not to merely extend the term given the nature of man - years of his life in a calendar year. Preserve and extend the full creativity, ability to work and the enjoyment of all good things in life - that's the problem! And this is the true happiness of longevity. But how to achieve anti-aging, extension of youth?
 
History shows repeated attempts to create an elixir of eternal youth, but they have not been successful. Even the ancient Greeks, claiming a real understanding of the problems of longevity and immortality to this fact allegorically one of the myths that have become cultural heritage of civilized humanity ...

Can I do without atherosclerosis, a disease that develops when every aging man? In other words, can a man in his old age to be younger in fact, reducing your biological age is at least half lived, calendar?
That raises a number of specific questions: when old age begins and ends when a youth, what are the signs of old age, how to determine the biological age of a person? It is appropriate to pose the question that if it is known at what point begins the retirement age, why can not there be differences in different people? And then, maybe, it would be fairer to retire, depending on the biological age, not by calendar (passport) terms? Will it, in turn, the ability to continue to man their professional work? Laws of these yet, but does that mean that they never will be? And yet, who will take to determine the biological age of a person? And there is a real need for this?
