This assignment is the fourth of five original topical essays you are to write and post on the Discussion Board—and which I will be using (in lieu of exams) to assess your mastery of course material. When posting, type or paste directly into the Messages box so that your readers will not have to open attached files (use attachments only for supplementary materials such as photos). In this essay, you are to discuss the following: (1) What are some of the major SOCIAL implications of biological changes (e.g., declines in vision, hearing, and mobility) that come with aging? (2) Aging can also alter mental functions such as learning and memory. How do all these changes affect the daily lives of both the aging individual and those with whom she or he interacts (or might interact)? (3) Also consider dangerous risk factors associated with hospital stays in older people, and effective ways of guarding against these risks. (4) Finally, describe in detail one or two real (or true-to-life hypothetical) case examples of older adults who are either struggling with or coping well with the physical and mental challenges they face. (5) What can people do to help maintain their faculties as they age?
