Superstitions as a whole

Superstition is a credulous belief or notion, not based on reason or knowledge. The word is often used pejoratively to refer to folk beliefs deemed irrational, which is appropriate since irrational means "not based on reason". This leads to some superstitions being called "old wives' tales". It is also commonly applied to beliefs and practices surrounding luck, prophecy and spiritual beings, particularly the irrational belief that future events can be foretold by specific unrelated prior events.

Many superstitions and old wives tales are passed down from families, i know my mum always mentions some of them, while other more unusual ones are forgotten of ignored. For example when mentioning this project and an idea of breaking a mirror my friend got rather freaked out by the idea. Its funny how we still do some of these old wives tales that were created for nothing more then to scare people into doing certain stuff.
How many of these are still relivent to the modern world and how many are still remembered? in my notebook im going to write down as many superstitions i can remember or think of, and get my friends to do the same.
