Aging is a natural phenomenon, specifying different stages of human life with a different level of physical and cognitive abilities. It works in a parabolic form, initiating from a weaker physical and mental stage of human in childhood, taking it towards the heights of physical and mental growth and development , and latterly a to decline in both powers in the elder age. This parabolic methodology can be modified to a very limited extent by using some artificial measure of medication, but cannot be altered completely.
