      • comment
      • new insight
        • life expectancy at birth skews our understanding of how the health and longevity of adults. -There is a false claim and belief that due to modern technologies, modern humans have lived far longer than our ancestors in the distant past.
        • In fact, child mortality rates play a major role in calculating life expectancy and this is what differs modernity from our ancestors.
        • Our distant ancestors did live to their 70s and 80s
    1. What is commonly known as ‘average life expectancy’ is technically ‘life expectancy at birth’.  In other words, it is the average number of years that a newborn baby can expect to live in a given society at a given time.  But life expectancy at birth is an unhelpful statistic if the goal is to compare the health and longevity of adults.  That is because a major determinant of life expectancy at birth is the child mortality rate which, in our ancient past, was extremely high, and this skews the life expectancy rate dramatically downward.
