hexakosioihexekontahexaphobia

According to this BBC news article, http://news.bbc.co.uk/2/hi/europe/5049516.stm , this is the fear of 666 or any representation of the number ... like 06/06/06. For us (think this is something I can safetly generalize) this is a totally irrelavant issue (Although I do hate the fact that the last Harry Potter would only be probably released on 07/07/07, although its already bloody finished)

So what I was going to ask was, very bluntly, how much of reality as we see it is based on what we believe? (A) All (B) 66% (C) 42% (D) None (E) None of the above.
Oh, and you have to follow up with your reasoning too!
