Your first name of Sinclair has made you a hard worker with a meticulous sense of detail. You are interested in facts and figures and do well in positions that require great attention to detail, such as accounting, computer technology, or in research. It is what you can see, experience, and prove through compilation of facts, experiment, and logic that has greatest value to you. Your lack of expression can lead to misunderstandings and unhappiness with those close to you who do not understand your practical, candid, somewhat self-centred approach. Since lavish affection embarrasses you, you do not appreciate being the target for endearing words. If developed, you have an ability to be inventive in practical fields of endeavour. You are serious and methodical. Your progress is built upon your meticulous awareness of detail, your patience, and your consistent hardworking qualities. Also, your fondness for heavier foods can affect the intestinal organs causing constipation, hemorrhoids, and even in severe cases, ulcers or growths. At times you find it difficult to express the depth of your feelings for those you love.
