Because that 80-year+ life span has nothing to do with developments in water treatment, sewage removal, housing, refrigeration, or discoveries of bacteria and viruses, developments of antibiotics, vaccines, insulin, or any of the myriad drugs for the myriad diseases and conditions which have been discovered. Nor medical/surgical/dental procedures with ever more delicate and, increasingly, non-invasive instruments. And advances in understanding the human body and its nutritional needs and ways to meet those needs, pre-birth to old-age. Not to mention hospitals that are no longer the germ-soaked, infection-spreading ... hum, forget this one.
