I'm not surperstitious either. I do sometimes say 'knock on wood' when I'm joking around, or cross my fingers, but not one piece of me believes that just doing, or saying, it would make a difference, lol.
Not me. I just can't believe how some people could be so supersitious to the point that they'll kill themselves because of what they believe in. I think it's madden, I think that's the worse thing so far that humans came up with.
