YES, im very superstitious!! I always salute to a magpie if i see just one on its own, I never put new shoes on the table, If i spill salt I always throw some over my left shoulder, (I think this is the correct way?) I knock on wood, and theres many many more. A black cat is deemed lucky over here, mo , you are right there but also white cats are lucky too!!
If I think of anymore Ill get back to you!!
