      • 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
    2. It is not uncommon to hear talk about how lucky we are to live in this age of scientific and medical advancement where antibiotics and vaccinations keep us living longer, while our poor ancient ancestors were lucky to live past the age of 35. Well this is not quite true. At best, it oversimplifies a complex issue, and at worst it is a blatant misrepresentation of statistics. Did ancient humans really just drop dead as they were entering their prime, or did some live long enough to see a wrinkle on their face?

    3. 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.

    1. The impact of this exclusion itself is impossible to measure, but increasing meritocratic inequality has coincided with the opioid epidemic, a sharp increase in “deaths of despair,” and an unprecedented fall in life expectancy concentrated in poor and middle-class communities.

      Are these all actually related to meritocratic inequality? What other drivers might there be?

      A discussion of the life expectancy of a comic.

      What they miss here is that it's easier to produce if you're also consuming a lot of material, particularly in a group. The output is proportion to the input, and at the time there was only so much input that one could take in in a much sparser media market in comparison to 2021.
