Specialists from the Institute of Applied International Studies drew attention to modern retirees. As it turned out, the appearance and physical form of the current elderly people is much better than fifty years ago.
The development of medicine, nutrition and lifestyle have had a positive effect on people.
Experts believe that to relate a person to the elderly is necessary for 15 years before his death. In some countries, the average duration of the population reaches 90 years, and therefore the old age in people should be about 75 years.
The head of the study, Sergei Shcherbov, noted that the concept of age is changing and will continue to change in the future, as quality and life expectancy are increasing.
Two centuries ago, sixty-year-old people were considered ancient old men, but now these people can be attributed more to the mature than to the old. According to demographers in the future, a person in 50 years will look at 30, and live people will be more than 90 years while maintaining their activity for as long as possible.
However, it is worth considering that life expectancy for each country has its own, in addition, differs by gender.
For example, in Japan, women on average live 86 years, men 79 years, in France 84 years women and 78 years men, in Russia and Ukraine - men live on average 64-65 years, women - 76 years. In Japan, men's old age begins at age 61, and for women from 71 years old, for Europeans, old age comes with 63 years for men, with 69 for women, in Russia and Ukraine - from 49 years for men, 61 years for women.
In another study, experts at the University of London said that people who feel younger than their current age are at lower risk of death.
About 6 thousand people took part in the experiment, which the scientists observed for 8 years. During the study, 14% of those who felt younger than their years died, and among those who felt themselves to be older or older - 25%.
As a result, the scientists concluded that optimism and a sense of youth create a kind of protection, thanks to which people live longer.
Other researchers have found in the human brain a certain area that contributes to the prolongation of life. It is proved that chromosomes contain a certain program according to which the body begins to fade and die, but the "control center" of this "program" is laid in the brain.
Specialists of the medical college in the United States tried to determine how different tissues of the body began to age, whether there was a definite impetus to this, or everything happens spontaneously. And, as it turned out, there is a control center that regulates the processes of tissue growth, metabolic processes, reproductive work of organs.
During experiments with rodents, scientists drew attention to the main sign of old age of tissues - a strong sensitivity to inflammation. The protein complex, which signaled inflammation, reached its maximum concentration in the hypothalamus and blocked the synthesis of the GnRH protein. Specialists suggested that aging is caused by a decrease in the level of GnRH. After carrying out a series of experiments, they confirmed their hypothesis (rodents lived 20% longer as a result of GnRH administration or a decrease in the level of the protein complex signaling inflammation).
Scientists are sure that in the same way you can influence the hypothalamus of a person and prolong youth.
