It found that cleaner air had lengthened life expectancy by five months in 51 U.S.cities Researchers at Brigham Young University and Harvard School of Public Health found that average life expectancy increased by three years between 1980 and 2000 in those cities, and that approximately five months of that gain owed to cleaner air.
