The daily deluge of health studies, reports and statistics is often meandering and confusing.
After all, sometimes a report will contradict the findings of another, issued just days earlier. More often, snapshots of the American experience are revealed in the numbers at the bottom of an abstract statistic, parked far away from the statistic shouting the loudest up top.
