Before 1946, conquering disease would have seemed as much a subject of science fiction as putting a man on the moon. But since 1950, global life expectancy has risen by four years each decade. Smallpox has been eradicated, and polio and malaria cases have dramatically fallen. Within the past 80 years, there have perhaps been more significant advances in human health than there were in the previous 300,000.
