While I’m neither a ‘Rat not do I play one at the voting booth, I can attest to the effects of CO2. I was in the bottom of a 7-story tall cavern working on a hydroelectric turbine when I was overcome by CO2, probably from welding gases, and hauled off to the hospital with my eyes rolled back in my head (or so I was told).
