1.0 INTRODUCTION: According to some formal definitions of aging: Oxford defines general aging as the process of change in the properties of a material occurring over a period, either spontaneously or through deliberate action. Biological aging is simply defined in oxford dictionary as the process of being old. The term "aging" refers to the biological process of growing older in a deleterious sense, what some authors call "senescence" (Williams, 1957; Comfort, 1964; Finch, 1990). Aging is defined as the process of becoming older, a process that is genetically determined and environmentally modulated (Rogina B, Reenan RA, Nilsen SP, and Helfand SL, 2000). To expatiate on the formal definitions mentioned above, living organisms are nothing but Gerontology overlaps with numerous other fields such as physiology, psychology and sociology hence it is multidisciplinary in nature. Gerontologists view aging in terms of four distinct processes: chronological aging, biological aging, psychological aging, and social aging. Chronological aging is the definition of aging based on a person's years lived from birth. Biological aging refers to the physical changes that reduce the efficiency of organ systems. Psychological aging includes the changes that occur in sensory and perceptual processes, cognitive abilities, adaptive capacity, and It involves interdisciplinary research on biological aging's causes, effects, and mechanisms. Biomedical gerontology, also known as experimental gerontology and life extension, is a sub-discipline of biogerontology that endeavors to slow, prevent, and even reverse aging in both humans and animals. By preventing senescent changes in animals, these therapies would prevent the onset of age-related disease and frailty, extending both average and maximum lifespan. Most "life extensionists" believe the human life span can be increased within the next century, if not sooner.
1.0.6 Effects of aging on humans Many common characteristic features of aging are observed by most of humans during their life span from birth to death, few of them as listed below: • The ability to hear high frequency sounds above 20kHz is lost in teenage years. • After a peak in cognitive performance a progressive decline begins and continues here after in the mid 20s. • Photoaging causes wrinkles particularly affecting the sun exposed areas by the age of 30. • There is a sharp decline in female fertility after age 35. • Presbyopia in eyes becomes apparent in the mid
surpassed since perspectives on aging have progressed. As we age our very own biology puts us at risk for health issues; however, many older adults can be healthy and active well into their advancing years. It is an established medical and societal fact, that eating healthy along with exercise and physical activity can help promote healthy aging, but are there other factors that a person can instill into their daily routine that may aid in the age-defying process? The NIA and other studies are researching…
Later years, means older age. Age comes in many forms, chronological, biological, psychological and social (Ebersole, 2005). Simply by considering these different characteristics of age, demonstrates how multidimensional ageing is. It is certainly not a matter of putting people into chronological age categories, and professing that they will all experience the same life course. People are diverse and age does not always discriminate. Nevertheless, ageing in later life is associated (at least in Western…
the rise in estrogen in her body. Annie’s Physical Transformation The biggest and obvious developmental change in Annie’s body will be growth spurts. When it comes to Norma she is 78 and aging is a progressive, predictable process in which gradual changes not caused by disease or accident occur over time. Aging affects both body and mind. Some age-related changes start at early as the 20s others may not appear until people are in their 70s like Norma. While Norma is in the…
Effects of Antioxidants in Anti-Aging Every aerobic organism on this planet contains within them many different chemical processes, most occurring at fast rates and on a constant basis. For example, the conversion of oxygen gas to carbon dioxide gas as we inhale and exhale. Often times during a chemical reaction, unwanted products become expelled through a natural course. The human body is built to withstand the tests of time for the most part; however as we age the trillions of cells in our…
Anna C. HEALTH CARE FOR THE GOLDEN AGED In chapter 1 of Joralemon, importance is placed on a symbiotic complex of biological processes. Medical anthropology has illustrated interference in patience versus clinal setting as a culture. The practice of medicine and it’s implication in anthropology are deeply inter- linked with society, disease and medical professionals. The social demographic which is an epitome of a frequent health care user are older people. The existence of a state…
1. The elements that comprise successful aging are generally very subjectively defined. Some might narrowly define successful aging based on an individual’s career advancement and or wealth accrual. Others may prioritize an individual quality of life, particularly with regards to the individual’s health, as the determinant of successful aging. “Successful aging is holistically defined by the avoidance of disease and disability, maintenance of mental and physical function, and continuance of engagement…
In the book, Morrie does not allow the disease to consume him, but rather he uses each moment to teach. The book touches basis on Morrie’s life review, which is the process by which people assess their lives, recalling and evaluating their past (Steinberg, p. 573). Through this process Morrie was able to find meaning and purpose within his life. He passed this knowledge onto Mitch when he told him “So many people walk around with a meaningless life. This is because they’re…

coding of a defective gene and that is why this could allow us to cure those diseases because they all stem from a defective gene. It could also lead to increased life expectancy due to the altering of our genetic code, we could alter how we develop biological in order to not age so quickly. The other side of the coin to this debate is that who are we to play god because he is our maker and put us here to do his business for his plan is divine and everything has a reason. Throughout this paper I am going…
treatment facilities are designed to speed up the natural purification process that occurs in natural waters and to remove contaminants in wastewater that might otherwise interfere with the natural process in the receiving waters • Wastewater contains varying quantities of suspended and floating solids, organic matter, and fragments of debris • Conventional wastewater treatment systems are combinations of physical, biological and sometimes chemical processes to remove these impurities 1 Treatment…
