13.2.1 Biological Changes

Each person experiences age-related changes based on many factors. Biological factors, such as molecular and cellular changes, are called primary aging, while aging that occurs due to controllable factors, such as lack of physical exercise and poor diet, is called secondary aging (Whitbourne and Whitbourne 2010).

Most people begin to see signs of aging after fifty years old, when they notice the physical markers of age. Skin becomes thinner, drier, and less elastic. Wrinkles form. Hair begins to thin and gray. Men prone to balding start losing hair. The difficulty or relative ease with which people adapt to these changes is dependent in part on the meaning given to aging by their particular culture. A culture that values youthfulness and beauty above all else leads to a negative perception of growing old. Conversely, a culture that reveres the elderly for their life experience and wisdom contributes to a more positive perception of what it means to grow old.

The effects of aging can feel daunting, and sometimes the fear of physical changes (like declining energy, food sensitivity, and loss of hearing and vision) is more challenging to deal with than the changes themselves. The way people perceive physical aging is largely dependent on how they were socialized. If people can accept the changes in their bodies as a natural process of aging, the changes will not seem as frightening.

According to the federal Administration on Aging (2011), in 2009 fewer people over sixty-five years old assessed their health as “excellent” or “very good” (41.6 percent) compared to those aged eighteen to sixty-four (64.4 percent). Evaluating data from the National Center for Health Statistics and the U.S. Bureau of Labor Statistics, the Administration on Aging found that from 2006 to 2008, the most frequently reported health issues for those over sixty-five years old included arthritis (50 percent), hypertension (38 percent), heart disease (32 percent), and cancer (22 percent). About 27 percent of people age sixty and older are considered obese by current medical standards. Parker and Thorslund (2006) found that while the trend is toward steady improvement in most disability measures, there is a concomitant increase in functional impairments (disability) and chronic diseases. At the same time, medical advances have reduced some of the disabling effects of those diseases (Crimmins 2004).

Some impacts of aging are gender-specific. Some of the disadvantages aging women face arise from long-standing social gender roles. For example, Social Security favors men over women, inasmuch as women do not earn Social Security benefits for the unpaid labor they perform (usually at home) as an extension of their gender roles. In the healthcare field, elderly female patients are more likely than elderly men to see their healthcare concerns trivialized (Sharp 1995) and are more likely to have their health issues labeled psychosomatic (Munch 2004). Another female-specific aspect of aging is that mass-media outlets often depict elderly females in terms of negative stereotypes and as less successful than older men (Bazzini and Mclntosh I997).

For men, the process of aging—and society’s response to and support of the experience—may be quite different. The gradual decrease in male sexual performance that occurs as a result of primary aging is medicalized and constructed as needing treatment (Marshall and Katz 2002) so that a man may maintain a sense of youthful masculinity. On the other hand, aging men have fewer opportunities to assert their masculine identities in the company of other men (for example, through sports participation) (Drummond 1998). And some social scientists have observed that the aging male body is depicted in the Western world as genderless (Spector-Mersel 2006).
