In the near future, people may live for 200 or even 300 years. There is evidence to support this opinion, of course.
Humanity has been trying to find the secrets of longevity since ancient times. Ponce de Mons, a Spanish researcher who lived in America, believed that the human body has a "fountain of youth", Professor Mechnikov "the poison of old age", and Siolkovsky "feeling and thinking atoms", and conducted many scientific studies on this matter. According to the opinion of contemporary gerontologists (experts in the science of life extension), people may live 200 or even 300 years in the near future. There is evidence to support this opinion, of course.
I think there is a difference between truth and reality. Perhaps it is true that theoretically human beings can live longer. However, if, as has been said, human beings will live 200 or 300 years, this means that there will be more population and in an exponential way, that is to say there will be billions of human being and therefore not everyone will have access to food, water and care (depletion of resources) which can lead to a high mortality rate and the human being again cannot will only be able to live for a few decades but this time in much worse living conditions than those of today.
