Your first name of Hannigan makes you quick-minded, versatile, and very expressive. Your extreme sensitivity and intensity have an adverse effect on your nervous system and, under extreme pressure, could cause a nervous breakdown. Farther fields look greener to you and you find it hard to finish what you have started. Through lack of discretion and being too emotional, you could attract bitter experiences and disappointments in people. A poor memory could eventually be a problem. You could, at times, be too easily influenced against your better judgment and be led into activities that put you at risk. You make the effort to communicate with others because you place importance on having people like you. The qualities in this name tend to narrow your opportunities by making it difficult for you to concentrate. These upsets drain your vitality and make you tire more readily. It could also cause upsets in the fluid functions: in the kidneys, bladder, or circulatory system of your body.
