The typical pattern of handwriting, letter forms, and so on is restricted to a certain group, age, language, and so on. Individual traits: These features are unique to a certain writer. This distinguishes handwriting. It may also be used to identify an author of a document, especially if the writing is far from perfect. Handwriting is an individual trait transmitted by our genes. It is very stable over time and not easily faked. Some people think that writing with a pen makes a mark on paper; actually, it only creates a shadow of what was written earlier with another ink. The actual physical making of letters is done with the hand and fingers, which changes every time we write something new. Our hands are subject to many factors including but not limited to age, gender, and lifestyle choices such as smoking and drinking alcohol. In conclusion, handwriting is an individual trait transmitted by our genes.
