A phool and his money are soon parted. People know so little of how the world works that anyone who spouts a little semi-scientific mumbo-jumbo can be rich very easily. Look at homeopathic "medicine".
I have a somewhat related story. A fellow class member saw that I had the same laptop as his (a new model). He asked me how much I bought the extended battery for and said something like "It must have cost you around $200 right?" I calmly replied "50" because he had previously told me he bought his for $200. After I said that he was like "WhaAaat?" and put his head in his hands. To make him feel better I said that I didn't get the warranty for the battery. He obviously wasn't aware that you could buy the battery on eBay without going through HP. Look around and compare prices! Or else you're gonna get ripped off.
When one person suffers from a delusion it is called insanity. When many people suffer from a delusion it is called religion.
