I've gotten these bogus Nostradamus quotes emailed to me 3 times.
to debunk, go to this link to Concordance.com and click on "Nostradamus-- Prophecies."
as K. says, "Type in key words and get actual quotes.... You'll note the absence of any references to 'twin brothers' or 'york'... some of his myriad ramblings are sure to end up sounding like a true prediction, just out of random chance."
