UNIT 1: OVERVIEW OF AGING 1.3 THEORIES OF AGING

Among the theories on aging, biological theories are a group of theories based on the aging of organs and systems. These theories have great difficulty boarding, because it is difficult to separate what is due to the aging of what is its effect.

The aging manifests itself in a number of alterations in each level of biological organization. These theories consider aging as well as growth, is determined by the information in our genes. Discussing certain programmed processes or attributed to the aging process as a result of aging or of an accumulation of errors in DNA and RNA synthesis.

Therefore, its essential purposes are:

- To understand how aging occurs at the molecular level in cells, tissues and body systems

- Analyze how it affects the mind-body relationship to aging and individual chromosomes in the general process of aging.

This requires understanding how it works the aging of cells, systems and influences how chronological age and the different conditions in each individual.

In contrast, psychological theories have focused on cognitive, personality and management strategies. Here, aging is more than a physiological process, involving a complex interaction of phenomena including psychological and social components.

These aging theories are based on the transformation of the human body after the age of physical maturity, transformation of appearance, behavior, experience and social roles. Also, it is based on individuals grow and age as a result of heredity and environment. They deal with the organization of behavior in the adult years, and attempts to explain how political causes, economic, legal, etc. may influence the way the individual accepts his age. And the ultimate goal with these theories is to predict successful aging.

CONCLUSIONS

Undoubtedly, there are many causes that cause our bodies age, there is no single cause, a single theory or a single explanation for this, as they are multiple factors that lead to aging.

Different biological theories on aging pose different views on the possible causes, over time, will alter our body slowly deteriorating it, causing the gradual aging and bringing it closer to leaving the service.
