Você entendeu TUDO ERRADO sobre a idade dos humanos antigos

Why do so many people say that everyone used to die at thirty? The answer lies in a very common misconception: life expectancy at birth is not the same as the typical age of death for an adult. When many babies and children die young, the average drops, even if some survivors reach middle age and old age. In this video, the question "why did ancient humans die young?" is investigated through a more precise approach: infant mortality, infections without antibiotics, risky childbirth, famine, contaminated water, injuries, environmental crises, and lack of sanitation, vaccination, and safe surgery. The goal is to correct the myth without romanticizing the past. We also explain why life in prehistory and antiquity cannot be summarized by a simple phrase. Hunter-gatherer peoples, ancient farmers, and historical populations faced different risks. The correct answer is not "everyone died at thirty," but rather that many people did not survive the first stages of life. #prehistory #human evolution #ancient history #anthropology #science MAIN REFERENCES USED 1.
