Simul8,
Here's one of the many definitions of 'myth' that Google just threw up:
"Something not true, fiction, or falsehood. A truth disguised and distorted."
Here's what wiki has to say about 'urban myths':
"An
urban legend or
urban myth is similar to a modern folklore consisting of stories thought to be factual by those circulating them."
In light of that, do you understand what Nick's point is?
