We are not sure about anything in the world except the aging. We are approaching getting nearer to the death from the time of the birth onwards. No living thing in the world has the ability to defeat death as…
This paper briefly explains some of the biological theories of aging mentioned above.
Simple Deterioration Theory argues that Aging is the accumulative result of universal deteriorative processes such as oxidation, molecular damage, wear and tear, or accumulation of adverse byproducts (Goldsmith, p.3). Even though man and machine are two entirely different things, both of them have certain similarities in their functioning. No machine is able to function more than particular period of time because of the wear and tear due to continuous work. Same way bodies of the living things are also undergoing continuous work which causes damages to the parts of the body. Even though we refill the fuels in the form of food, nutrients and water, there are certain limitations for the body of the living things to survive for a longer period. In chemistry, most of the chemical reactions yield products and by-products. These by-products are not necessarily the intended one. Same way our body chemistry also yields different by-products which are harmful to our health and may reduce our life span. At the same time we cannot avoid the production of such by-products
Non-programmed theory of aging believes that aging is a passive result of an organism’s inability to better resist fundamental deteriorative processes. Moreover aging serves no purpose, is not an adaptation, and is not programmed (Goldsmith, p.8). Our body is undergoing lot of changes and processes virtually in very seconds. Most of the activities inside our body are beyond our control. For example, the pumping of blood by the heart is not done with our permission. We cannot stop any of the internal functions. Everything inside our body is tuned to do certain things and any malfunctions occur inside our body may result in diseases. We are passive observers of our body functions.
“Organisms are purposely designed and genetically programmed to age or ...

The body functions cease to be the same as they used to be years before. They tend to become much slower or faster in body functions, and the mind ceases to function as it used to. Ageism is the process by which discrimination is brought against all those who are old, and the aging process.
Abstract Melatonin is a hormone produced in the brain from the amino acid tryptophan within the pineal. It is a naturally occurring compound and it is found in animals, human beings, plants and microbes. The general level of melatonin vary greatly throughout one’s life cycle, the first time melatonin is secreted is when a child is three months old and that is when most people starts to sleep.
The theories are based on the premise that the physical attributes are passed from parents to the children making such children fall at the risk of committing crimes. Major theorists in this field studied the body organs of individuals relating the attributes of certain body organs to criminality.
Even though many evolutionary theories of aging and longevity were proposed by prominent anthropologists and biologists in the past, the mutation accumulation theory and the antagonistic pleiotropy theory are the most prominent theirs accepted by the scientific world at present.
Some researchers have come up with theories to explain the personality changes that people in their late adulthood experience. Through these studies, there have been many successful aging theories that have been suggested by renowned psychologists. Today, many psychologists believe that as adults approach their old age, their behaviors change and they develop new personalities.
Chronological aging defines aging based on person’s number of years since birth while psychological aging includes the changes in perceptual and sensory processes that individual face during their life. Some psychological changes that are associated with aging include changes decline in memory capability, intelligence decline and changes in both values and personality of an individual (Scheibe & Carstensen, 2010, p 142).
Humanity has always been intrigued by the question of why human beings age since the beginning of time. Every person may desire to live forever, but who looks forward to getting old? We hope we are vigorous right up until the very end. Still, day to day, many of us make unhealthy choices that could put our future at risk.
