amicabl: Common knowledge
Well, if you are going on that premise...that "common knowledge" is accurate, I dunno what to say, especially when this thread is about science.
Because, when I examine your observations about a 19th century cemetery that you visited, it becomes apparent that your "common" knowledge arises from your myopic view of the world that didn't allow you to observe the large number of maternal deaths that cemeteries of that age "commonly" hold.
Skewed statistics? Yes, your interpretations and observations are skewed. You leave out women in your observations.
