Your first name of Siderio creates an idealistic, sensitive nature and a desire for culture and the refinements of life. The result is intense moods of depression and the tendency, at times, to be secretive. The inclination to daydream needs to be curbed as it is detrimental to mental progress. Therefore you find it difficult to express your thoughts freely, with the result that people do not find it easy to get to know you well. With training you could be artistically creative as you have an appreciation for music and the arts. You could be subject to glandular disturbances, poor circulation, kidney or urinary tract disorders, and, later in life, prostate problems. You would work best in a relaxed environment at tasks involving writing, mathematical, or analytical skills that require concentration. While your name brings you some fine qualities, these are overshadowed by the effect it has on your physical body. It is most important for you to establish a nutritious diet and exercise in order to build a strong, vital body. Procrastination is a weakness, for so often you are inclined to avoid issues and to leave things undone until the last moment when you are forced to take action.
