Someone tried telling me that this is true. I see where they had a study that said it 'may' cause it but nothing even close to conclusive. Anyone support or oppose this study? Just curious, my wife believes it because her mother told her it was true who is Jehova's Witness. I think she's just overly paranoid and quite obviously subject to misdirection through words.
