Carbon monoxide danger. A sense of perspective
Sometimes our leaders are dumber than a sack of rocks. They assssssume everyone "out there" has a double digit IQ. "Look Dick look. See Jane run" does not cut it for many people.
You don't have to read the cut n paste from Wikipedia if you don't want to - no one is pointing a gun at you. The following is an excerpt. See if you can ascertain the # 1 frightening fact about carbon monoxide and absorption into the blood...
The binding of oxygen is affected by molecules such as carbon monoxide (CO) (for example, from tobacco smoking, car exhaust, and incomplete combustion in furnaces). CO competes with oxygen at the heme binding site. Hemoglobin binding affinity for CO is 250 times greater than its affinity for oxygen, meaning that small amounts of CO dramatically reduce hemoglobin's ability to transport oxygen. Since carbon monoxide is a colorless, odorless and tasteless gas, and poses a potentially fatal threat, detectors have become commercially available to warn of dangerous levels in residences. When hemoglobin combines with CO, it forms a very bright red compound called carboxyhemoglobin, which may cause the skin of CO poisoning victims to appear pink in death, instead of white or blue. When inspired air contains CO levels as low as 0.02%, headache and nausea occur; if the CO concentration is increased to 0.1%, unconsciousness will follow. In heavy smokers, up to 20% of the oxygen-active sites can be blocked by CO.
