This small, cheap device could save your life one day Everyone knows how dangerous Carbon Monoxide is, but a lot of people believe that it won't happen to them. But just as smoke alarms were scarce, and still are rare in many communities, despite being required by law , the detectors are probably missing in most homes. Just like the last story on male breast cancer, this one has a personal take, not me, but my parents this time. They recently had an incident where a detector very well could have saved their lives so I am glad they had one. Here is my dad's account. Thanks dad for chronicling what hopefully will open others' eyes.
