Redhead Superstition: Fact or Fiction?

In some cultures, redheads are associated with bad luck. A recent video highlighted a superstition in Argentina where individuals, upon seeing a redhead, must touch a specific body part to avoid misfortune. Men touch their left testicle, while women touch their left breast. While the video's presenter claims this is a genuine belief, further investigation is needed to confirm the prevalence and origins of this tradition. The video's popularity, however, suggests a significant interest in the topic.
