| Abstract: |
Handwriting is the formation of letters, characters, or symbols, using writing implement according to a recognizable pattern, which is designed to communicate with another person. Handwriting is usually done with the fingers and hand, connected to the writer’s body by his arm. They contain many nerves and muscles that can affect the writer before, during, and after the act of writing. This movement is controlled and coordinated by the brain.There are several definitions of aging have been put forward, and indeed aging has many different aspects. It has social, psychological (behavioral), physiological morphological, cellular and molecular aspects and a definition encompassing them all does not seem possible. Biologists involved in the study of aging operate on the premise that aging is characterized by a failure to maintain homeostasis under conditions of physiological stress, and that this failure is associated with a decrease in viability and an increase in vulnerability of the individual.Aging is obviously a function of time, but development and maturation also involve changes, which are age (time)-related. However, both of the later processes lead to the attainment of peak physiological function, whereas the above definition implies that aging is a deteriorative process. In aging one can experience changes in fine motor coordination, large-muscle control, and both visual and auditory function. This can affect day-to-day activities like dressing, driving, and handwriting.
