Your first name of Johnaia has made you systematic and practical in all you do. You quickly spot inefficiency and can be somewhat intolerant of others as a result. You think carefully before committing yourself and you are not easily influenced against your better judgment. You are clever in mathematics and have great patience with work of a detailed nature, such as bookkeeping or accounting. This name limits imagination, flexibility, responsiveness, and spontaneity in your nature. You like to make things function efficiently and could be inventive along practical lines. Your seeming lack of emotional display causes others to regard you as somewhat insensitive. You have a good memory for details. Through wrong eating and tension, weaknesses in the physical body could appear in the digestive system or in the reproductive organs of the body. Your very practical nature does not allow you the appreciation you might have for life's more aesthetic values as it keeps your mind mostly concerned with facts and figures.
