It is true, as the article correctly points out, people often misinterpret average life expectancy, because they don't fully take on board the impact of child mortality.

(I admit to knowing nothing about the social dynamics of ye olde anciente humanse; I'm just assuming that once you're of biological age, you become incredibly likely to get knocked up.)
