Your name of Doncan gives you a clever, analytical mind, and causes you to be studious and serious, drawn to the deeper secrets of life. You are drawn to the silence and beauty of nature; that is where you rebuild your energies and find peace of mind. You sense there is much that cannot be understood by the five senses. There could be misunderstandings in relationships because you feel deeply about those you love but are embarrassed to openly show your affections. It takes a confident person to read from your quiet thoughtful gestures that he or she is held in high regard. However, in your personal life, this reserve and reticence are often mistaken for coldness and lack of feeling, with the result that others find it difficult to understand you. Also, tensions can arise with those close to you because of your tendency to be secretive with your own thoughts and plans, yet at times interfering in the affairs of others. You could earn the respect of others with your ability to remain calm and in control while facing challenging situations, even if internally you are experiencing turbulence. Physical weaknesses are relative to your heart and respiratory system where you could suffer with palpitations, shortness of breath, chest colds, bronchitis, asthma, or pneumonia. As it is not easy for you to share your deeper thoughts and ideals with others, you are inclined to choose the association of those few friends with whom you feel the most at ease and with whom you can enjoy companionship in a contemplative mood without feeling pressure for verbal communication.
