Go ahead and get your tattoo, i,m sure you will not have to answer to anyone why you have one. Religious or otherwise. But make sure you really want one, it,s the trend at the moment, but i,m starting to see reports that people who have them now wish they did not. Tattoo,s do have a religious background any ways. They were for protection against bad luck and to show that you were religious with your body paintings. They originated in Asia, then the sailors of the world copy them . Enjoy your new tattoo.
