If only 160 die per year, it is unlikely that thousands get sick each year. On the same point 100's die each year for lack of buckling seat belts that are already there. Houses burn down and people die because they're too stupid or too cheap to replace batteries in smoke alarms. What I'm saying is that CO in the home is a tiny problem in the scheme of things that will not be appreciably solved by people buying CO detectors. If you want a more pressing problem try addressing the thousands of child deaths because their parents store bad stuff within the childs reach. Now if you can get them to turn their brains on you would save 2-3000 each year instead of 160 people. The name of the game is Priorities.
