I just saw some clips of a documentary that stated something about plastics being somewhat dangerous for males because it heightens the estrogen levels and causes some endocrine system disruptions. I admittedly didn't understand everything that was said but I'm guessing that was the gist of it. It was said that the chemicals could even be found in baby bottles which I think is very scary, but also it exists in almost all plastic products as well so everyone should be more alert. Do you guys pay attention to the type of plastics you use? How do you avoid or identify which ones are safe and which ones aren't?
