Cancer

I definitely don't believe that reusing a water bottle can cause cancer. Some of this is abosolutly rediculous. I do believe that reusing a water bottle can break down chemicals in it, like what Janet said, but those are what make the plastic and it would have to take alot of reusing that water bottle to break it down, even then i dont think that any of the chemicals are harmful enough to cause cancer. To go to what Dan said about things being "Known to the State of California to cause cancer." I read that new car smell is "Known to the State of California to cause cancer." Really? New car smell? You got to be serious!
