Gerontology deals with the study of biological, psychological and social aspects of elderly. This field is differentiated from the study of diseases of elderly which is termed geriatrics. Gerontology has two subfields: biogerontology and geroscience. Biogerontology studies the process of growing old while geroscience studies the relationships between natural aging process and adding due to diseases.

The field of gerontology is not as structured or advanced like other fields despite the multidisciplinary nature. The is may be due to lack of institutional support required for advancing gerontology as a comparatively low number of universities offer higher degrees in this field. Nonetheless, gerontology has received much advancement particularly in the Western nations where elderly population is significantly increasing. Accordingly, this field is at present a well-paying profession for many Western citizens.

Drafting step is the stage upon which the ideas are shaped into paragraphs and sentences by the writer. A draft is writer-centered and a step upon which the writer connects and merges his ideas and integrates them into explanations by putting them into words. The writer often changes his words in order to support his ideas in a coherent manner and may choose additional; ideas and implications to further his writing. At the draft stage, no attention is given to spellings or grammar corrections. The draft is basically to gather the writer’s different ideas and views on the topic.

Gerontology also investigates the physical and mental changes as people grow old as well as the social changes due to aging. A number of fields are associated with gerontology such as sociology and psychology but these sub-fields overlap and cannot be regarded as same. For instance, a psychologist may only be a gerontologist if he specializes in older adults as a psychologist specializing in early adults is not a gerontologist.
