How many years can a person live?

At the moment, human life expectancy is about 70 – 75 years. But there are also long-livers who survived 75 years and even reached 110 years of age. But every year life expectancy decreases and more and more people die at the age of 60-70 years. All this speaks about the decline of ecology on earth and the deterioration of the way of life of the world’s population, pollution of the atmosphere. In order for the world’s population to be able to increase life expectancy, it is necessary to deal with ecology.
