The name of Jona creates a quiet, systematic, and technical nature and a clever, inventive mind, attentive to detail. You would find electricity, electronics, and similar technical fields of interest, as well as computer, mathematical, and scientific studies. The workings of mechanical, electrical, and electronic equipment intrigue you. You are also drawn to working out-of-doors in nature. Your aversion to administration responsibilities, sales, or promotional activities is also a limitation. You are inclined to be quiet, reserved, patient, and conservative, preferring to test and prove everything to your own satisfaction before committing yourself. Because you do not openly share your thoughts and deep feelings, you are not easy to understand and those close to you, not sure of your affections, may assume you do not care. Finding it difficult to join in light conversation with those with whom you are not well acquainted, you could feel quite alone and uncommunicative. An inclination towards heavy foods such as meats and starches could cause eliminative problems resulting in growths or tumours in your gastrointestinal tract. Also, you could experience sensitivity in your heart, lungs, and bronchial organs.
