Any superstitions?

1. Bad luck opening an umbrella in the house.

2. Breaking a mirror and that leads 7 years of bad luck.

3. My family and i eat black eyed pease for new years. Good luck.

4. Walking underneath a ladder bad luck.

Um that is about all. I don't really believe in this good luck and bad luck stuff. Don't they have a book for these kind of susperstitions anyways? Or do a search through google or yahoo.
