Errrm
I don't get it, if the guard was breathing oxygen from his helmet, then what the hell was the black guy breathing. I have a guess that he was still tipping from all those colurs around him. Note just becasus a computer has over a million colurs you don't have to use them all in one go. Oh and by the way when breathing out you don't produce carbon dioxide, that would be crazy, its just left over from when the oxygen has been taken out from the air breathed out, plus all the other hundreeds of gases found in the air. AND BREATH...
