I'm not superstitious, but I love superstition. I'm big into science, mythology, and religion (I would actually like to be able to study as much of them as possible, but it's kinda difficult to do all three) because they all seem to be related in some way. For instance, Zombies are scientifically proven (though not in the way we think of) and the explanation is from voodoo, which is connected to certain religion. So, Zombies are a link between religion, myth, and science.

Opening an umbrella inside was a sign of disrespect to the sun god since they were originally used on sunny days. Walking under a ladder was bad luck because you were disrupting the holy shape of the triangle, and I don't remember the origin of the mirror.
