thefickler writes "A new study by the US National Institute of Environmental Health Sciences (NIEHS) has found a strong link between air quality and life expectancy. The researchers looked at air pollution, deaths and census data for 51 metropolitan areas between 1978 and 2001, and what they found was a direct correlation between improving air quality and extending life expectancy. People lived about 2.72 years longer over that time span and at least 15 percent of that increased life expectancy was from a decrease in air pollution."

Yes, pollution concentration and contents changes over times and you need a methodology to keep track of these things. If common sense was a viable guide to life than we wouldn't need science.
