Your first name of Yoona has created a practical, patient, scientific nature able to concentrate on the finer details of a project or undertaking. You enjoy learning from discussions, but express your deeper thoughts and feelings better through writing. It is difficult for you to find lasting happiness in association because you are exacting, fixed in your ideas, and inclined to be secretive. You do not like to be interrupted or hurried once you start a project. Lack of proper verbal and emotional expression creates intensity and unhappiness within you, which in turn disturbs your nervous system and depletes your vitality. You would function best in settled conditions where you are not called upon to meet and mix too closely with others, but are able to work on your own. You would find enjoyment and peace in an outdoor environment studying the flora and fauna of nature from a scientific point of view. This name restricts congenial expression and association, creating much aloneness. You may also experience some deafness. Other health problems could affect the lungs, heart, or bronchial organs.
