How did have a itchy right palm become a good luck sign?

The belief that an itchy right palm signifies good luck stems from various cultural superstitions. In many traditions, an itchy right palm is thought to indicate that money or good fortune is on its way, often associated with receiving money or a financial windfall. This idea may have originated from the notion that the right side of the body is linked to positive energy and fortune, while the left side is sometimes associated with loss or misfortune. Over time, these beliefs have been passed down, reinforcing the idea of an itchy right palm as a sign of impending good luck.
