Everyone surely has some lucky or unlucky superstition which means they will flail wildly when faced with a ladder, or just completely avoid a footpath with cracks in it, or stops their mirror breaking hobby (I'm exaggerating, I think)
In doing the poll, I had to try and get the more common ones, living in England, we have some incredibly wacky ones, like this gem:
"Cut your hair when the moon is waxing and you will have good luck!"
Or this one:
"One ancient British superstition holds that if a child rides on a Bear's back it will be protected from whooping-cough" (Though not protected from a right mauling)
Do you have any little known superstitions?
