Your name of Carl gives you a strong urge for independence. You prefer to be alone with your own thoughts, rather than in the company of others. Once you get an idea, you forge ahead, despite obstacles, until you reach the end of your project. Investigating and studying various aspects of nature, for example, as an astronomer or naturalist, appeal to your desire to seek an understanding of life. Yet, when they get to know you, they realize you are loyal in friendships and would go to any length to help someone in need. A physically active person, you have an appreciation for outdoor recreation, which you prefer to pursue on your own or with one or two close friends who share the same affinity for the peace of nature and the physical challenges it provides. Neither sentimental nor idealistic, you take life as it comes and learn as you go. You find your own solutions and innovations to get a job done, without relying on encouragement or assistance from others. You work best where you can combine physical labour and prefer to work where you can spend time outdoors. The health weaknesses due to the influence of this name could cause you to suffer either with headaches, weak eyes, sinus problems, lung and bronchial disorders such as asthma or emphysema, or a heart condition.
