Your first name of Landis has given you a quick, analytical mind. Any criticism from others causes you to retaliate cuttingly in self-defense. 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. In your dealings with people you place great importance in living up to one's word. Family and friends find it hard to understand you because of your changing moods, and because of your intolerance and indifference towards their ideas, interests, and feelings. Your self-sufficient and self-reliant nature gave you the urge to leave home early in life to be free from parental restraint, and to establish your independence and freedom from tradition. You expect as much from others in return but find, either through misunderstanding or lack of principle in others, you are often let down, leaving you feeling bitter and betrayed. Routine, monotony, and the responsibility of looking after details can have a similar effect on you, as you are a person who desires change, travel, and new experiences. Ailments could also centre in the head causing headaches, sinus problems, or defective eyesight, hearing, or teeth.
