Do you know how long humans lived in ancient times? You may often hear statisticians or historians describe the lifespan of human beings. Did our ancestors live only 30 or 40 years ago? This article will take you to learn more about the average lifespan and the longest lifespan of humans in history.
First, we need to understand the average lifespan of humans in a certain historical period and the length of individual lifespans during the same period. Until now, people have little information about how long people can live (length of life) in prehistoric times. Because people lack information about human fossils, it is difficult for historians to accurately estimate the population and lifespan of each era.
The length of life of prehistoric humans
Research teams such as professors of anthropology from Central Michigan State University and the University of California used the analysis of the relative age of bones excavated in archaeology to explore the lifespan of ancient humans. By comparing the proportion of people dying in childhood and dying in old age, they found that about 30,000 years ago, human life span was significantly longer, that is, more than 30 years old.
From antiquity to industrial period
The evolutionary biologist and geriatrician Caleb Finch described in the Proceedings of the National Academy of Sciences in 2010 that the average life span of humans was only 20 to 35 years in ancient Greece and Rome. Many researchers have pointed out that in the early century, a large part of people died from different kinds of infectious diseases, whether it was infectious diseases or various accidents and wound infections caused by wars.
Although the average life expectancy of human beings at that time was between 20 and 35 years old, it does not mean that everyone will not live to 35 years old. (There is a concept to understand here: average life expectancy refers to the average life expectancy of all populations in the same period) this number It is greatly affected by the level of infant mortality. Therefore, although the average life expectancy during that period was not long, there were still some people who could live to 60-70 years old. Research scholars pointed out that if people at that time were lucky enough to escape the risk of infection caused by various diseases and injuries before the age of 15, then these people might live longer. But even so, people at that time were still at high risk of various large-scale infectious diseases, such as cholera, smallpox, tuberculosis, etc., which could easily take people's lives. The most terrifying is the Black Death that swept a third of Europe's population in the 14th century.
19th century to present
For more than three hundred years before 1800, the average life expectancy across Europe has been hovering between 30 and 40 years old. Since 1800, due to the improvement of various sanitary conditions, people began to receive various immunizations, began to drink clean tap water, and the intake of various nutrients in diet continued to increase, and the average life expectancy at birth had doubled. However, in the early days, various diseases were still common, such as parasites, rheumatic fever, typhoid fever, and so on. With the continuous development of human medicine, the average life expectancy of most contemporary industrialized countries has exceeded 75 years.
Focus on the present and look forward to the future
With the progress of society and the improvement of various living standards, the average life expectancy of contemporary humans has achieved a relatively large increase. But this also brings bad news, that is, as people get older, people's risk of suffering from various diseases will become higher and higher. Such diseases include cancer, diabetes, dementia, coronary artery disease and so on. These will greatly affect the quality of life of the elderly.
Therefore, what we need more in our time is not just longevity, but healthy longevity. How to maintain a healthy and long-lived lifestyle? In order to prevent or delay various diseases, we can maintain regular biological exercises, maintain a healthy weight, follow an anti-aging diet, and maintain a reasonable level of stress hormones such as cortisol. At the same time, if we have the conditions, we can also use biological age testing equipment to learn about our biological age in advance, and regulate our physical condition in a targeted manner, and adjust our lifestyle to maintain a healthy and long life. You can also choose NAD+ supplements (NMN), which has been proven by most top scientific research professors to be highly effective in anti-aging, to delay aging and enjoy a healthy and long life.
If we maintain a healthy and long-lived lifestyle and dietary supplements, along with the continuous advancement of medical biotechnology, the average life expectancy of humans should exceed 100 years in the near future.
