How superstition gets a hold of us... people ward off bad vibes by getting tattoos of horseshoes, four-leaf clovers or dragons, which are one of the most popular tattoo designs (apparently dragons possess superior forces).
Other people feel the need to call upon divine power by displaying their religious and spiritual beliefs (a cross, Virgin Mary, crucifix or Buddha) on their bodies. We thereby grant notions of protection and magic powers to these indelible symbols. And if you have your lucky charm tattooed onto your bod you'd never be in danger of losing it.
