Superstition says that if your left palm itches that you will either spend or lose money. It is believed that you should rub the palm on something made of wood to counter the effect.
The old superstitions said: - if your left palm itches you will loose money. - if your right palm itches you will receive money or good news. Also it is said that if your right palm itches make a wish and then rub the palm with a bit of brass, "Rub with brass, make it come to pass." - if your left foot itches you will go on a short trip. - if your right foot itches you will go on a long journey. - if your nose itches you will kiss a fool.
