Your first name of Bertie has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You tend to express yourself in an opinionated, candid, and matter-of-fact manner. The repression and frustration that you may experience at challenging moments in your life cause nervous indigestion and, in the worst cases, could result in ulcers and severe stomach problems. When you are annoyed, you must guard against a strong temper and the expression of intolerance and criticism. You could experience a great deal of pleasure in outdoor physical activity or sports. Therefore, if anyone interferes with your activities or offers unsolicited advice, you are inclined to react defensively and express your feelings in a blunt and, at times, caustic manner. Your love for others is shown more in your loyalty and sense of fair play rather than in any overt demonstrations of love and affection. If, for some reason, you cannot carry out your plans, you can experience deep moods of depression. Intensity affects the senses of your head as well, whereby you could suffer with migraine headaches, sinus problems, or throat and swallowing difficulties. You become intensely involved with everything you plan to do, but the stress arising from frustrating obstacles or misunderstandings with others could prompt you to be intolerant and sarcastic in your expression, with breakdowns in congenial relations with family and friends a possible end result.
