Average human lifespan was dragged down by infant mortality. Where we have good data, people lived to about the same age as today - or even longer.[1] See, for example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2672390/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2672390/ [1] Obvious caveat that particularly awful periods of history in some locations had bad life expectancies - wars that killed a third of the population, the Black Plague, genocide, etc. The idea that human life expectancy has improved over time is a myth - unless you start counting in 1900. It's gone up and down throughout history, but ours is nothing special.
