Read this thread, especially LIP's two posts [the one that is pretty long...I agree with mostly everything and believe it's very accurate...then the one with all the sites backing it up].

Don't give them any negative info...if it's negative or sounds silly...that's because it is. 90% of the negative info out there is bullshit and most has been proven wrong with studies and science, not just what the government says.
