What is the statistics of life expectancy ?What is the main cause of aging?

According to the UN, average length of life on our planet is 63 years - for women and 60 years - for men .However, average figures do not show the possibilities of man: so life expectancy in the UK for women - 75.9 years for men - 69.9;in the United States for women - 78.3, men - 71.5;in Australia - 78.7 and 71.4 respectively;Finland - 78.5 and 70.2;France - 80.3 and 72.0;in Japan - 80.7 and 74.8;in Norway - 80.8 and 79.8 years.According to most gerontologists (gerontology - the science that studies various aspects of human aging, its causes and how to deal with it) the length of human life should be at least 90-100 years, and guarantee that the age of the oldest old.
However, scientists do not have specific recipes for prolonging life.So Academician VV Frolkis advanced adaptive-regulatory theory of age, according to which aging is caused by a change in the regulation of gene activity.He theorized vitaukta (anti-aging).This theory states that during the evolution of the genetic composition of populat
course, be wrong to assume that everything is predetermined and programmed!For example, it is known that centenarians are distributed very unevenly throughout the planet.Typically, the existence of "longevity oasis" associated with any local phenomenon (mountain air, sea and so on. D.), A general conclusion made Romanian researcher Marin Voiculescu.According to him, the longevity is ensured in an environment where we can maintain consistency running the biological clock.Let us explain a specific example: the researchers grew several generations of Drosophila flies in unnatural light conditions - in this alternation of light and darkness, a day when unequal obtained 24 hours.Life expectancy has fallen dramatically flies with it!Cause?She's the one - the violation of rhythm inherent in the body.
Yes, judge for yourself: we work - or when we "work", a snack - when you have a dream - when dropped from fatigue, etc. In our life very little measured...Violation of rhythm - it is a process, leading to more rapid extinction of life.In addition to the circadian rhythm, there is a kind of calendar showing the total change of rhythm from birth to old age.Soviet scientist, Professor VM Dilman named this clock hours "more biological clock."This watch, in fact, is measured not the rhythm, and his loss!How much time we have been given - the evolution of the set, and how much has already been spent - you can "try on" this watch.
As "ticking" clock - we all feel, though, and do not think about it.For example, all say that time with age "flies faster" - a natural sense of time is accelerating!It is believed that the newborn is "flying" 7 times slower than for a decade.Why?And because a newborn makes 7 times more physiological work, roughly speaking, it grows to 7 times faster.
It is also believed that the normal "turn arrows" Large biological clock - 13 years.In particular, every 13 years, the adaptation rate after exposure to bright light eye approximately halved.This pattern can be observed from 19 to 90 years.
daily rhythm loss eventually leads to the fact that the arrow turn makes for a shorter period of time.As a result, "younger" of the disease, life expectancy is reduced.It is not difficult to guess that having established circadian rhythm - can delay the "damage" Large biological clock.
