Your first name of Semtex has given you a quick, analytical mind. You are happy and in good spirits as long as headway is being made, but as soon as you feel obstructed or your individuality and freedom of action are curtailed, you experience an intense nervous reaction in your solar plexus. Competitive sports or challenging outdoor activities could bring you pleasure and relief from pent-up frustrations. In your dealings with people you place great importance in living up to one's word. Moods of depression can result during which you become caustic and belligerent in your attitude toward everyone, especially to those in closest association with you. Your nervous intensity could cause indigestion and, over time, could lead to ulcers and severe stomach problems. However, independence, positivity and the urge for action and progress are such strong forces in your nature that you find it difficult to control them. Although you are not demonstrative of your feelings in family relationships, you maintain a strong sense of loyalty. Ailments could also centre in the head causing headaches, sinus problems, or defective eyesight, hearing, or teeth. The effect of the nervous tension can appear in childhood as stuttering.
