NVDL: Interestingly the amount of high school graduates is also highly correlated to longevity. I'm guessing kids who stayed in school for the duration are less likely to kill their neighbours and steal from their parents, or is it the other way round?
BOSTON (Reuters) –
Dramatic improvements in U.S. air quality over the last two decades have added 21 weeks to the life of the average American, researchers reported on Wednesday.
Reducing fine particles given off by automobiles, diesel engines, steel mills and coal-fired power plants have added as much as 15 percent of the 2.72 years of extra longevity seen in the United States since the early 1980s, they wrote in the New England Journal of Medicine.
Improved socioeconomic conditions, judged partly by the proportion of high school graduates living in an area, rank next. But cleaner air was a big factor.
