Digital BW, The Print

Who said it was proven.  Sounds like a bunch of hooey to me.  

While toxic chems are not good, what is toxic in what way is generally blathered about 
rather than known.  Gasoline for ex is supposed to be bad, but we used to virtually bathe 
in it washing machine parts and I am healthy (and old).  Same for trichloroethylene; they 
virtually drowned rats in it which caused them to die (exposed to a zillion times higher 
dose than rational) so they banned it.  Really too bad.
