I've seen that site before. It's nice to keep in mind that we don't really know what we're putting in and on our bodies. A concern for a lot of people is not only that but also we don't know the long term results of using these ingredients/chemicals/stuffs, if there is a result from using them mixed together (over a long period of time... and by long, I mean decades), or if they accumulate in the body somehow. But, yeah, it's really unavoidable. But you CAN control how much you expose yourself to a degree.

But, stress will kill you too! Don't panic.
