Many have said that the development and process of progeria is overlapped by the normal process of aging. Can progeria be a model for the normal process of aging? Aging is often defined as a person growing older. However, we can’t ignore the fact that as we age we also suffer of diseases, and not just the physiological inadequacy (Dyer & Sinclair, 1998). At a rapid rate, cells get old and die throughout the whole organism, as well as normal cells that are differentiated. Cancer cells divide continuously and escape the process of deterioration of age. There is no current definite explanation in a variety of different species; however, chronically decreased energy intake prolongs life.
