Your name of Diaz has formed an independent, positive, and determined personality. You are rather skeptical of new ideas that are more visionary, idealistic, or philosophical. Activities combining ingenuity and manual skills are of particular interest enabling you to excel in technical vocations, for example, as a mechanical, electrical, or electronics technician. Humour and spontaneity are not natural expressions of this name. As you are not overly conversational, at times you consider time wasted when spent in idle chatter. As a result, this limitation causes repression and frustration at times. You are a realist with interests in mathematics and technical or scientific fields. Being somewhat wilful and skeptical, you learn best through your own experiences and seek proof though facts. Also, your fondness for heavier foods could affect the intestinal organs causing problems with elimination and, in severe cases, ulcers or growths. Health weaknesses centre in the head, resulting in such conditions as headaches, sinus problems, weak eyes, or impaired hearing.
