The name of Castor creates a quiet, systematic, and technical nature and a clever, inventive mind, attentive to detail. What you achieve is through meticulous planning and step-by-step hard work. You would find electricity, electronics, and similar technical fields of interest, as well as computer, mathematical, and scientific studies. You are inclined to be quiet, reserved, patient, and conservative, preferring to test and prove everything to your own satisfaction before committing yourself. Lack of communication can lead to misunderstandings and unhappiness in relationships and cause you to retreat into yourself and experience loneliness. Because you do not openly share your thoughts and deep feelings, you are not easy to understand and those close to you, not sure of your affections, may assume you do not care. You are studious, able to excel in subjects where intense concentration is required, and systematic and orderly in your approach to any undertaking. You are inclined to be quiet, reserved, patient, and conservative, preferring to test and prove everything to your own satisfaction before committing yourself. An inclination towards heavy foods such as meats and starches could cause eliminative problems resulting in growths or tumours in your gastrointestinal tract. Friendships and personal association are accordingly restricted, as well as business success, because you are over-cautious in venturing into financial risks or promotional effort.
