there are a few 70 and 80 year olds in the Cemetery,  but WAY too many babies and children.  Definitely messes with the averages

Yep. As it turns out, we really don’t know much about expanding the upper limits on human aging because we’ve never had the historical data sets we do now. Even in the 5th century BCE, good genes and economic class were the best predictors of longevity. The playwright Sophocles lived into his early 90’s. From the same time period we have literal wells in abandoned and poor Athenian neighborhoods with piles of infant remains infant remains inside. If you could survive birth, early childhood, and either childbirth or war, you stood a good chance of making it to old age.
