Representatives of science and adherents of variousworld religions have long argued about how many people live and can live. For example, the Bible tells us about a certain Mufusali, who was one of the forefathers of all mankind and lived on Earth for 969 years. Now the Guinness Book the oldest person on Earth calls the Japanese Kimura Jiroomeon with his 115 years of life. It is generally known only one reliable fact - women live much longer than the representatives of the stronger sex. So how much does an average person live on?
Since the Neanderthal period, archeologistscount the life expectancy of a person. Up to the Middle Ages people did not live more than thirty years. A lot of deadly diseases, lack of basic hygiene and many other external factors did not allow people to live long.
Hygiene was the first step to prolonging life. The invention and the subsequent improvement of the water supply and sewage system led to the fact that people began to live on average about 40 years. Louis Pasteur, who discovered the principle of vaccination in 1881, increased the human life for several more years. At that time people often lived to the age of 46-48 years. And the discovery by the Englishman A. Fleming in 1928 of the unique properties of penicillin gave people the opportunity to live up to 70 years. Around the same time, a whole branch of science was even created - gerontology, which studies all aspects of human aging: social, biological, psychological. In today's world, in developed countries, life expectancy is about 74-75 years.
In Pushkin's time in Russia, a thirty-yearthe woman was considered practically an old woman, and the man in fifty was a deep old man. In the twentieth century, the Soviet health system has made great strides, and this is in view of the three wars and two revolutions. In the 30 years, men in our country lived 40 years, and women - 45. By the sixties we reached the level of Europe in this matter. Then there were the hard seventies and nineties, but now the situation is getting better, albeit slowly. If you look at the statistics, now Russia is only on the 129th place in the list with 66 years of average life expectancy. The weak sex lives on average 73 years, and the strong, unfortunately, is much smaller - about 60 years.
Apparently, in different historical epochs the life of people has changed significantly. How many people live depends on such factors as:
