You are not overly conversational; in fact, at times, you consider time wasted when spent in idle chatter. Humour and spontaneity are not natural expressions of this name. You are interested in facts and figures and do well in positions that require great attention to detail, such as accounting, computer technology, or in research. You have a great deal of patience and independence, and you can be relied upon to complete your undertakings. The more deeply you feel about someone, the harder it is for you to express the little attentions and compliments that mean so much to some people. You are rather skeptical of new ideas that are more visionary, idealistic, or philosophical. Also, your fondness for heavier foods can affect the intestinal organs causing constipation, hemorrhoids, and even in severe cases, ulcers or growths. Health weaknesses of this name centre in the head, resulting in such conditions as headaches, sinus problems, weak eyes, or in extreme instances, loss of hearing.
