The life expectancy being shorter before modern medicine is missing context. People were more likely to die as infants, but if you made it to age 5, you would most likely live a modern life span of about 80 years, so infant mortality was greater, but if you were to survive past infancy, life expectancy is about the same as it is now.

That’s my understanding for mostcultures outside of cultures like the Inuit who died younger due to the lack of plants in the extremes they lived in.
