According to handwriting graphologists, a person's handwriting can say a lot about his personality, character and even medical problems. Graphologists consider the size, space, slant, shape of letters, page margins, pressure and other factors when analyzing a subject's handwriting.
According to graphologists, a person's handwriting can reveal over 5,000 personality traits. For example, people who have very large handwriting are often more outgoing and outspoken, while people with very small handwriting tend to be shy and withdrawn. The slant and shape of particular letters reveals whether a person is more logical or more idealistic, and the looping of specific letters like "e" or "l" reveals whether a person is open and spontaneous or closed and reserved. The space of margins left on a page reveals whether a person lives more in the past, present or future.
Many analysts believe that the study of handwriting can lead to a diagnosis of high blood pressure, Alzheimer's disease, schizophrenia or Parkinson's disease. For example, a symptom of Parkinson's disease is very small and cramped handwriting, and people with high blood pressure tend to exert varying pressure on a page while writing. Graphologists also believe that a person's handwriting can help to detect whether or not he is telling the truth.
