venicebeach's Journal: Superstitious behavior

I'm starting a research project on superstitious behavior. I thought this might be a good way to start to gather anecdotal data on what kinds of things people do superstitiously and why. Do you have any superstitions? Any unusual little things you do repeatedly for no reason? Tell me about them!

What is your superstition? When did it start? Why do you think you do it?
