IN SEARCH OF LONGEVITY AND ITS RELATION TO HUMAN SOCIETY SURVIVAL
Out of curiosity, I tried to determine two numbers, as posted in two questions below.
From the essay
Out of curiosity, I tried to determine two numbers. What is the minimum longevity of an individual to guarantee survival and progress of a human society? What is the projected maximum length of an individual that will lead to the society’s demise or the beginning of decline? My guess was 40 years for the minimum. Two generations allow for successfully passing down essential knowledge and skills, child-rearing, education, mentorship, and guidance.
