Psychic and the Psychic Network
    A psychic is someone who claims to be sensitive to extrasensory, nonphysical, or supernatural influences or forces. In many parts of the world, especially the US, there are people who claim that they can tell your future based on their psychic power. Very often, psychic reading in the US relies on tools such as tarot cards that originated in Northern Italy 500 years ago. Psychic reading in the US has become an entertainment industry by itself. You will find various psychic practitioners advertise their business (often called Psychic Network) on TVs , newspapers and other mass media. (A word of caution: Use your own judgment wisely when you visit psychic websites.)
