Are you aware that science has produced a study that says that the carbon levels in big cities actually acts as a stress reducer on people who live in these cities?

A study coming out of Israel has found that exposure to carbon monoxide in the air of big cities actually has a “calming” effect on the people who live in these big cities? I wonder if this could be the reason that so many people do not grasp the reality of Global Warming? Could it be that they are suffering from a build-up of carbon monoxide in their brains? The link I put at the start of this explanation is a link to the results of the study.
