First of all, consider the sources. Yahoo and Redbook aren't exactly pillars of journalistic integrity. Second, just look at that list. PVC Shower curtains? Seriously? Out of all the health risks out there (smoking, drinking, substance abuse, poor eating habits, lack of sleep, etc..) someone out there thought "hey, I bet that plastic shower curtain that I might brush up against for 10 minutes everyday is a super deadly health hazard." Ugh... sorry for the rant, but I really do wonder sometimes, who comes up with this stuff?
What does HN think about #3 Microwaving in plastic?
Or #1 for that matter? As far as I know most if not all studies have found no correlation between using cell phones and brain cancer. Yet the risk of having a car accident is not reduced by using a hands-free head set vs. just your cell phone. At least so I've heard, I would be interested to know if HNers have more information regarding these two points.
