Long Ago, our ancestors usually ended their lives in the stomachs of predators. Once you get older so that could not in time to hear approaching predators or do not have time to escape quickly and climb the tree, so welcome to their meals, as a snack. Since then, hundreds of thousands of years, people from the victims of the predators he was the most brutal predator on Earth. How many people now live and which die? In antiquity people had a life expectancy of approximately 30 years. Centuries have passed, life expectancy is gradually but very slowly grew, until in the last century it is not ripped up a giant jerk. The development of medicine and competent obstetric care has drastically, more than an order of magnitude, to reduce child mortality. But thanks to vaccinations, gone terrible epidemic that once ravaged the whole country. According to scientists, during the Neolithic, people lived an average of 21 years. Then the conditions of human life improved somewhat, and since the Copper age until the middle of XVIII century the average life expectancy of people on Earth made up from 31 to 35 years. During the Neolithic, people lived 21 godfathe: Source Then life expectancy in civilized countries began to grow, reaching Europe and the United States at the end of the last century 76-77 years. However, in Asian countries, life expectancy has declined from 40 years in the distant past up to 30-33 in the twentieth century. So the average life expectancy in the world remains from 36 to 66 years... until the XX century, the main cause of low life expectancy was a huge infant mortality. In childbirth often died and the baby and the mother, many children died before the age of 5 years. In addition, many dangerous diseases, which nowadays are easily treated, in the nineteenth century was fatal. Pneumonia, measles, smallpox, cholera, plague, dysentery... All those diseases, from which in our time or vaccinations in childhood, or have drugs, almost certainly their healing. Tuberculosis, a disease which in the XIX century was brought to the grave many residents, today is not considered life-threatening.

Yes, pneumonia is treated — the thing to run. Yes, venereal disease is no longer fatal, as it was only a century ago. Take a course of injections and any "Neapolitan" disease will disappear like a bad dream. The main thing — time to start to heal. But instead there are new diseases. HIV, hepatitis C became known to people only recently. In this cases they know that these diseases are not treated. Those who have contracted HIV or hepatitis C, you need to spend a lot of money just to stay healthy, then the disease remains in a chronic form, passing in the acute clinical form, because this means a strong rise in the cost of treatment and, unfortunately, impending death. Although the proportion of deaths from HIV is less than 3% of the total. About as many lives each year and carries hepatitis C. Photo: Depositphotos From what is nowadays most often people die? Diseases of the heart and blood vessels responsible for 31% of deaths. Cardiovascular disease — the scourge of our time.Communicable diseases account for about 11% of deaths.For diseases of the respiratory system, respiratory infections and infections of the lower respiratory tract also contributes about 11% of deaths.Various types of cancer responsible for 14,69% of the total number of deaths. Most of the remaining diseases in the statistics give a fraction of a percent of the total mortality. Each. I must admit that the statistics often hides information than it shows. How is the differentiation of causes of death by age? Because each of us is familiar (or familiar) with people once possessed of excellent health, which is a lifetime no disease took, died in very old age... old age. The once mighty organism after a certain age starts to weaken, aging, bones become brittle, weak heart, memory if quite disappears. And the argument begins to limp: the man that it seems he can't remember and execute once completely familiar to his manipulation, to do what he did decades every day. And easy cold suddenly leads him to death... many people past 80 years, there are particular senile diseases: dementia, Alzheimer's disease, bone fragility (osteoporosis). Today elderly people are suffering from diseases that were previously known, but they were not so massive, because in the past people simply could not live up to these diseases. Photo: Depositphotos nowadays doctors are working to cure osteoporosis, dementia and Alzheimer's disease. In the treatment of these diseases is a huge success. A little more time — and with the help of new drugs and the elderly will be able to overcome the known disease, while retaining activity, health and clarity of mind. While scientists suggest that people have a biological age limit a little more than 150 years. Today, many inhabitants of Western Europe and the United States can live up to 80-90 years, at least up to 100 years or more. The question: once people learn to treat diseases of old age, known in our time, allowing to live a normal active life and at the age of 100 years, what new "diseases of old age" appear? Because, you see, you can't live forever!...
