Please. Can you really walk "unseen among people or crowds?" I don't believe it.
But if you really can become invisible as this book says, Britney Spears has to buy this. And Oprah. I am sooo sick of seeing these people in the tabloids.
Judging by the comments in this guy's feedback, all this guy is selling is books about making yourself invisible and bringing in good money. WHAT?!?!? I have heard of people wanting something for nothing, but not nothing for something.
