Your name of Thach has formed an independent, positive, and determined personality. You are more interested in being active and accomplishing the tasks you set for yourself. As you are not overly conversational, at times you consider time wasted when spent in idle chatter. Humour and spontaneity are not natural expressions of this name. It is what you can see, experience, and prove through compilation of facts, experiment, and logic that has greatest value to you. You do not have great ambitions and your requirements in life are moderate. You are interested in facts and figures and do well in positions that require great attention to detail, such as accounting or computer technology. You are fussy about details and seek perfection in whatever you undertake. Health weaknesses centre in the head, resulting in such conditions as headaches, sinus problems, weak eyes, or impaired hearing. Also, your fondness for heavier foods could affect the intestinal organs causing problems with elimination and, in severe cases, ulcers or growths.
