@Merry Andrew,
Quote:I agree with Green Witch that the greatly increased longevity of recent times is due more to better health care and development of better medical practice (including anti-biotics and other drugs) than to elimination of the causes of early demise.
I find that rather problematic . . . if one does not survive infancy, or early childhood, an improved medical care delivery system won't benefit you very much. I only stated that the introduction of the automobile lead to the most significant single improvement in public health in human history. I didn't say that there were no other significant improvements. Dr. Snow's use of demographics to create modern epidemiological study in the suppression of disease (cholera in his case) was surely significant. Vaccination was significant. The introduction of sulfa drugs was significant. But none of them had the effect that the removal of horses from the urban environment has done. Now, anything which would have removed draft animals would have worked--in truth, it was not just the automobile, but the growth of urban public transit systems, as well. But epidemiologists are pretty well agreed that the most dramatic effect in public health was achieved with the removal of draft animals from cities. Most of the diseases to be associated with automobile exhausts have been respiratory, and cannot necessarily be said to have had as deletrious an effect on public health as did the presence of tons of manure in city streets, nor the vectors for tuberculosis. Even lead in the air from automobile exhaust cannot be said to be a cause of fatal morbidity, although it may have created many dull-witted children.
For that matter, the work of Margaret Sanger and other early "feminists" who wanted to end the deaths of women from the constant bearing of children and the then common "child bed fever" had a much more important effect on the health of women than did any amount of antibiotics.
It is interesting, though, that you note that a solution to one problem may be a problem in itself. We have, in a few decades, selected in the evolutionatry sense for bacteria which are antibiotic-resistant.
