Why Do We Agereview The Materials For This Week Andin Your Own Word
Why do we age? Review the materials for this week and in your own words summarize 3 theories or hypotheses that explain why our bodies age.
In the US and abroad, cosmetic surgery is tremendously popular. Many patients who request cosmetic surgery do so wishing to regain their once youthful appearance. Why do you think Americans are so concerned with the outward signs of aging, most of which are relatively harmless? Is this a positive or a negative social trend? Explain and support your response.

The phenomenon of aging has been a subject of both scientific inquiry and social interest for centuries. Understanding why our bodies age involves exploring various biological theories that provide insights into the physiological and genetic mechanisms driving the aging process. Moreover, societal perceptions and cultural trends significantly influence how aging is experienced and addressed, especially in contexts such as cosmetic surgery.
Biological Theories of Aging
One of the most prominent explanations for aging is the Programmed Theories, which suggest that aging results from genetic programming within our cells. This includes theories like the genetic clock theory, which posits that our genes contain an internal clock that dictates the lifespan and initiates aging processes at a predetermined time (López-Otín et al., 2013). Similarly, the immune system decline theory argues that aging occurs as the immune system weakens over time, reducing the body's capacity to fight off diseases and repair tissues (Goronzy & Weyand, 2017).
Another significant hypothesis is the Damage or Wear-and-Tear Theory, which views aging as the cumulative result of environmental damage and cellular wear over years. This damage includes oxidative stress damaging DNA, proteins, and cell membranes, primarily caused by free radicals (Harman, 1956). This process results in the gradual decline of cell function and tissue integrity, ultimately leading to age-related deterioration (Finkel & Holbrook, 2000). The wear-and-tear theory emphasizes the impact of external factors like pollution, UV radiation, and lifestyle choices, which accelerate cellular damage.
Lastly, the Telomere Theory of Aging offers a molecular explanation, suggesting that the shortening of telomeres—the protective caps at the ends of chromosomes—limits the number of times cells can divide. As telomeres shorten with each cell division, they eventually reach a critically short length that triggers cell senescence or apoptosis, leading to tissue aging and functional decline (Shay & Wright, 2005). This theory links cellular aging directly to genetic mechanisms and the replication lifespan of cells.
Societal Concern with Outward Signs of Aging & Cosmetic Surgery
The heightened concern with outward signs of aging, especially seen in the popularity of cosmetic surgery in the US and globally, reflects deep-rooted societal values. Many Americans and individuals worldwide equate youthful appearance with attractiveness, vitality, and social desirability. Media portrayals often reinforce these ideals, emphasizing the importance of staying youthful as a symbol of success and desirability (Pierre & Boursier, 2019).
Most signs of aging, like wrinkles or sagging skin, are relatively harmless but are perceived as markers of diminished attractiveness or social competence. Consequently, many opt for cosmetic procedures to mask these signs and maintain a youthful image. This fixation sometimes stems from societal pressures to conform to beauty standards that favor youthfulness, which can perpetuate a cycle of aging anxiety and cosmetic interventions.
Whether this societal trend is positive or negative is subjective. On one hand, cosmetic surgery can boost individuals' self-esteem, confidence, and overall mental health, contributing positively to their quality of life (Fabi et al., 2017). On the other hand, it might promote superficiality, reinforce ageism, and place unnecessary emphasis on external appearance rather than internal qualities. The obsession with youth can also lead to unrealistic beauty standards, fostering societal pressures that contribute to mental health issues such as body dysmorphic disorder and depression (Cash, 2012).
Conclusion
Overall, aging is a complex interplay of biological processes and societal influences. Biological theories like genetic programming, damage accumulation, and telomere shortening help explain the physiological decline associated with aging. Meanwhile, cultural values and media influence shape societal perceptions, often emphasizing youthful appearances at potential psychological or social costs. Recognizing these factors can foster a more balanced perspective on aging—appreciating natural biological processes while challenging superficial standards that unduly emphasize external appearance.
