As I told you correlational studies do not and cannot provide a cause/effect. If a correlation is all you have then you have nothing with regard to proof.

Can I prove that it does not? A negative is, by its nature, impossible to prove. Then again, I'm not the one who is demanding action based upon my beliefs and no proof.
President Reagan summed it up nicely, "Some people go through their entire lives wondering if they made a difference, Marines don't have that problem!!!"
