Dozing off in a meeting? It could be the air. Greenhouse gases aren't great for us indoors, either.

CO2may be a reason why board meetings often turn into "bored" meetings.

▼ Ever sit in a meeting or lecture wondering why time slows down to an agonizing pace and your eyelids suddenly feel as if they weigh two tons? You’re not alone, and you just might be pin your suffering on the 21st Century’s most infamous molecule.
Carbon dioxide, the greenhouse gas we love to hate, doesn’t just wreak havoc on the atmosphere at high concentrations—it’s in the air all around us, even indoors. Because humans exhale CO2, enclosed spaces we occupy tend to have much greater concentrations of the gas than outside. The more people there are per unit of space, the faster the CO2 level in the air within that space will rise. And without proper ventilation, it can reach numbers that would make an atmospheric scientist shudder.
Adam Ginsburg, a research fellow at the National Radio Astronomy Observatory, recorded this process in real time last week at the “Linking the Milky Way and Nearby Galaxies” academic conference in Helsinki. He used a small air quality monitor plugged into his computer to track the CO2 concentration in the conference meeting room and found that it peaked far above the 1000 to 1200 parts per million maximum indoor level recommendedby the American Society of Heating, Refrigerating, and Air-Conditioning Engineers.

So that is why it happens to me huh? Now I know whom to blame :-P
