People dying from second hand smoke is almost certainly a myth perpetuated by the media. Think of it this way, there are people, namely smokers, who directly inhale cigarette smoke, in many cases for decades, directly into their lungs. They certainly have a higher incidence of smoking related illnesses and deaths, but aren't exactly dropping like flies. But your telling me, that somebody who indirectly also breathes in smoke diffused through the air also has a significant increased chance of smoking related illnesses? Patently absurd, use some common sense. AM is right, should be more concerned about real dangers, like auto safety, than living in fear of some remote and in all likelihood non-threat.
