You cannot be pushed or driven, responding instead with great effort if you are approached with proper consideration. Lack of attention to details by others can be very frustrating. You have an inquisitive, investigative mind and a curiosity about life, along with an interest in scientific matters. In fact, you feel awkward and self-conscious when put in delicate situations, as you feel your inability to be as diplomatic as you should be. You could be inventive along practical, mechanical lines. This skepticism has not protected you from many disappointments when people you have trusted have let you down. The intensity created by the use of this name creates stomach and intestinal disorders such as ulcers, growths, or constipation.
