This is a serious question, as for thousands of years, humankind has believed that they have the ability of controlling their environment through metaphysical processes.

For example, the use of incantations while performing specific rituals is often believed to have effects on either those performing the rituals or others not present. These incantations and rituals can have either a positive or negative effect on the intended target(s).

Additionally, there are those that believe that certain symbols will either ward off bad luck or attract good luck, such as those tattooed on sailors arms.

There are many more examples, some very simple, like an architect's avoidance of labeling a thirteenth floor in a building.

So I wanted to see your reaction to this thought, and hear what you have to say.

Is it all bullshit? Or is there some legitimacy to this?
