YouTube video (creator/upload: Dr. Ron Najafi) discussing historical changes in life expectancy: the speaker states life expectancy rose from 47 to 76 in the first half of the 20th century primarily due to three factors—vaccination, sanitation, and antibiotics—and attributes ~30 years of increased lifespan to those causes. The speaker also warns that chronic diseases are now reversing gains and shortening lives.
