The Effects of Calorie Restriction on Aging by christiano
Introduction
For ages, humans have been searching for ways to counteract the aging process. The legendary fountain of youth generated much attention in the past, and more recently, thousands of dollars have been spent each year on creams, pills, plastic surgery, and various forms of therapy designed to make one look and feel younger. So far nothing has been proven to reverse or even retard human aging, but scientists are finally catching a glimpse as to a dietary manipulation technique that might work.
Preliminary Experimentation
In the 1930s, Clive McCay, a scientist at the laboratories at Cornell University, experimented on his rats by feeding them less than they would ordinarily take for themselves, but without depriving them of nutrition to the point of starvation. He found that the food-deprived rats lived considerably longer than expected for a standard rat's life span, and about 33 percent longer than his control group of rats, which were fed as much as they wanted to eat (Weindruch 46). McCay didn't fully understand his results, and although published, they were generally disregarded by the science world (Man Immortal).
Years later, Roy Walford, a nutritionist working at the University of California at Los Angeles Medical Center, came across the documentation of McCay's experiments, and, using modern technology and mice instead of rats, picked up where McCay had left off (Man Immortal).
Walford found that for the best results to achieve the longest life extension in his mice with the fewest negative side effects, calories should be restricted by 30 percent of what would be taken freely by the mice, and essential nutrients must still be consumed (Mlot 162). Dietary reduction of other things, such as fat intake, may be beneficial to health, but it does nothing to extend life span (Whitlock). Mice…...

...Assignment 2: Aging John Doe SOC 100: Introduction to Sociology Professor Beth Stewart May 3, 2013 For years, life expectancy has grown in nations across the globe. With ever changing technology and improving quality of life, people generally have the luxury of a longer life. That said, there things that need to be considered such as financial support for the elderly, retirement age, assisted living and self-sufficiency. At some point, living long changes from a luxury to a burden. There are social issues regarding the way that elderly are viewed in society. In many cases, this may lead to people trying to fight aging or to take better care of themselves so that they age gracefully. There are differences in the life expectancies of different countries as well as differences in how the elderly are viewed and respected in different cultures. In 1950, the life expectancy for girls born in India was 36 years while girls born in the US had a life expectancy of 72 years (Lubben, J. & Rodriguez, J.,2011). Another interesting statistic is that in 1900, only 21 percent of people had a living grandparent and in the year 2000, that number grew to 76 percent (Lubben, J. & Rodriguez, J.,2011). As life expectancy grows, the effected generations need to consider how they will support themselves. They need to consider how much money they need to have saved in order to live after retirement. Additionally, the retirement age has gone up as life expectancy has......

...old in politics hold most government positions which they would not want to leave making the youth feel more oppressed. Children base their views of aging and the aged mainly on the exposure they encounter. If a child's exposure to older people is based on negatively biased literature, media, and family influences, stereotypic and negative views of older people will likely become incorporated into his or her frame of reference (Seefeldt, Galpor, Serock, & Jantz, 1977; 1978). Studies of children's attitudes toward aging and old people have demonstrated that most children have negative attitudes and very limited knowledge of and contact with older people (Chappell, 1977 and Driver, 1981). What people do in order not to look aged or old A recent survey by the National Consumers League (2004) found that many Americans purchase products and go through medical procedures to hide the physical indicators of their age such as skin and hair including lifestyle. These products include creams or makeups that hide spots in old age, do away with or reduce wrinkles in their skin, and hair dye to change their hair color from grey to a more “youthful-looking” color because grey hair is associated with old age. Plastic surgery is increasingly popular, as a way to attempt to stay looking younger. As men age, a very common physical sign of aging is the loss of hair on their head. Men, it appears are just as afraid of looking older as women are, as evidenced by the popularity of toupees,......

...Aging Isn’t ironic how most people enjoy having birthdays coming up but they don’t not like the idea of getting old. Birthdays and getting old should always be a celebration of life. However, looking through the nearsighted eyes of a youth oriented society, many people tend to see birthdays past the age 29 as a sign for loss, including my self. My sister turned 29 very recently, and she has always enjoyed celebrating her birthdays, but definitely not this year around, she did not want to celebrate it at all. And her exact word was “I can’t believe I will be 30 next year”. She made me not to look forward to that age. What make us so afraid of getting old? Is it really the fear of getting wrinkles, or is it because we associate aging with getting closer to the grave? Sigmund Freud has a "death wish" theory. He believed that the natural state of objects is to be inanimate and that life is an aberration. For this reason, he concluded, every animate object longs to return to its inanimate state. That state is death. According to Sigmund Freud, there exist two conflicting forces in a being. Part of it wants to die and part of it wants to live. This causes tension. I know most human being don’t wish to die. And most of us are afraid of getting old because deep down we are afraid of getting close to die. Now, I know that most individuals have no conscious wish to die. Being optimistic is about hoping for......

Aging Effects on Population

...Aging Population Effects on Health Care Health care is a fast evolving field with advancements of technology and treatment options growing every day. The delivery of care has grown and often shifts direction over the years to accommodate changing population demographics and needs of patients. Many factors play a part in the role of health care and medical treatment, one of those factors being population demographic changes. When the demographics of a population change it can cause adverse effects on the surrounding area in many ways, such as access to care, types of treatment needed to care for the population and the need for health care employees. In a particular population where the demographic is aging the dynamic and need for care begins to affect the health care system in a variety of ways. All health care entities involved play a role in ensuring the challenges and the needs of the population change are met. As the population demographic ages, the impact on the delivery of care will be significantly altered such as the organization of care and how it is delivered, treatment options, long-term care, and health care coverage will all be affected in different ways. According to the Administration on Aging of the Department of Health and Human Services, approximately 13% of the people living in the United States are elderly as of 2011, which average to about 40 million people. The Department of Health and Human Services estimates that by the year 2030, this number will......

Murphy PSY 317: Cognitive Functioning in the Elderly Professor Rhonda Travland Ashford University August 26, 2013 Running head: WEEK 5 FINAL ASSIGNMENT: PSYCHOLOGY OF AGING 2 Abstract Aging in the United States raises challenges in terms of belonging, especially for older people. The interrelationship between aging and a sense of belonging is complicated because the aging process itself is influenced by many factors, including biological, sociological, psychological, economical, and attitudinal factors. Each of these factors has a unique impact on aging. Exacerbating these factors are society’s negative stereotypes and myths, discrimination, biases, prejudices, and negative attitudes toward the older people, which are cumulatively identified as ageism for the purposes of this paper. Thinking about the dimensions of aging for older people gives rise to a number of questions. For example, what are our cultural attitudes and traditions towards aging? How do these attitudes and traditions inform our private thoughts and public policies towards aging? This paper will focus on the mysteries that control human lifespan which are yet to be unraveled.

...Effects of Aging on Cognitive Development Natasha Veruchi PSYCH 640 3/30/14 Professor Weisz Effects of Aging on Cognitive Development As the society moves more towards the technological age, there also are advancements in medical technology that can prolong one’s life and solve medical issues that may be threatening one’s life. In the following paragraphs, there will be an evaluation of the effects of aging on cognitive development. These effects consist of physical decline as well as decline of one’s ability to obtain knowledge through their senses. There will also be examples provided to support the points as they are stated. Working with the older population one comes to realize that the majority of the older population will develop some form of dementia or Alzheimer’s. Cognitive frailty is emerging as the highest of health issue for the older population. As Bishop, Lue,and Yanker discusses as the life expectancy increases so does the onset of dementia and Alzheimer’s (2010). Aging effects several changes in the brain, as we grow older, the part of the brain that is responsible for cognitive functions show less coordination. As one ages, parts of the brain become inactive and others are affected by age even when they are free of disease (Bishop, Lue, and Yanker, 2010). There are certain cognitive processes that are relevant to one learning new information and trying to remember the information learned. A general downward spiral of overt attention......

Lonliness Answer the following questions in 100 to 200 words each. Provide citations for all the sources you use. • What is ageism? How does ageism influence the presence of diversity in society? Ageism is prejudice and discrimination against older adults. (Schaefer, 2012) It is a set of beliefs, attitudes, norms, and values used to justify age based prejudice, discrimination, and subordination. This may be casual or systematic. The term was coined in 1969 by Robert Neil Butler to describe discrimination against seniors, and patterned on sexism and racism. Butler defined ageism as a combination of three connected elements. • What is the Age Discriminitation in Employment Act (ADEA)? How does the ADEA address issues for the aging population? The federal Age Discrimination in Employment Act (ADEA), which went into effect in 1968, was passed to protect workers 40 years of age or older from being fired because of their age and replaced with younger workers who presumably would receive lower salaries. The Supreme Court strengthened federal protection against age discrimination in 1996, ruling unanimously that such lawsuits can be successful even if an older worker is replaced by someone older than 40.......

Research shows good communication with customers and organizations ensures a meticulous understanding of a distinct problem. Subsequently a program can be designed to meet needs and expectations of customers and organizations (Trott, 2004). Successfully solving problems with program software requires planning, analyzing, and program management to ensure all aspects of the problem meet the required expectations. I believe planning your program following the program development cycle, will enable you to use your time efficiently thus helping design error-free programs that produce the desired output. In the development cycle a programmer needs to first understand the problem by a extracting the requirements or requirements specification (Bronson & Rosenthal, 2005). The programmer then needs to analyze requirements using the information given to provide a repeatable, predictable process that improves productivity and quality results. Then coding takes place by writing statements in computer language to carry out the program design (Bronson & Rosenthal, 2005). After the program has been implemented software testing or validation......

Effects of Aging on Cognitive Development

...Effects of Aging on Cognitive Development Daphney Walker PSYCH/640 May 5, 2014 Holly Berry Effects of Aging on Cognitive Development Aging is a natural process of life however, studies show that there are some age-related decline in cognitive development. As a person grows older some brain cell dies, shrink, or weaken and cause some decline in brain functions. Some cognitive processes include attention, working memory, long-term memory, perception, and executive control. The material will explain the effect of aging on cognitive development by providing scholarly research proof. Cognitive Development Cognition is the process by which human beings learn about the world and the objects in it and also understand the relationship between themselves, the objects, and themselves. It is the ability of a person to learn and understand from his or her experiences, to acquire and retain knowledge to use in new situations, and solve problems. Cognitive development refers to the process of growth to the intellectual or mental abilities such as thinking, reasoning, and understanding. Cognitive development includes acquiring and condensing of knowledge. Social-emotional, language, perceptual, motor and environment experiences aid in cognitive development in infant. Piaget’s development theory gives an understanding of cognitive development from birth to adulthood. He postulated that when a child enters the world he or she lacks the cognitive competencies that an adult has.......

...older adults by environmental exposures. Biologic capacity declines with normal aging; this may be exacerbated in individuals with pre-existing health conditions. This decline can result in compromised pharmacokinetic and pharmacodynamic responses to environmental exposures encountered in daily activities. In recognition of this issue, the U.S. Environmental Protection Agency (EPA) is developing a research agenda on the environment and older adults. The U.S. EPA proposes to apply an environmental public health paradigm to better understand the relationships between external pollution sources → human exposures → internal dose → early biologic effect → adverse health effects for older adults. The initial challenge will be using information about aging-related changes in exposure, pharmacokinetic, and pharmacodynamic factors to identify susceptible subgroups within the diverse population of older adults. These changes may interact with specific diseases of aging or medications used to treat these conditions. Constructs such as “frailty” may help to capture some of the diversity in the older adult population. Data are needed regarding a) behavior/activity patterns and exposure to the pollutants in the microenvironments of older adults; b) changes in absorption, distribution, metabolism, and excretion with aging; c) alterations in reserve capacity that alter the body’s ability to compensate for the effects of environmental exposures; and d) strategies for effective communication......

...The Effects of Telomerase on Aging Over the past thousands of years, mankind has sought ways to live forever. Legends such as the fountain of youth and the philosopher’s stone have helped to spark fascination and curiosity about the possibility of eternal life. While the philosopher’s stone and fountain of youth were only ancient myths, modern biological research might have uncovered a process that might help humans live longer, healthier lives. This process involves an, until recently, little-known enzyme called telomerase. However, before telomerase can be defined, one must understand the aging process in which it’s used and why it’s so important. Human cells are constantly dividing. Whether they’re skin cells attempting to help replenish the epidermis or bone cells participating in bone remodeling, cells constantly need to replicate. When somatic cells divide, they do so through a process known as mitosis. During this process, chromosomes create duplicates of themselves in order to make a new cell. Chromosomes are able to accurately replicate themselves many times because of protective “caps” on their ends called telomeres. According to Scientific American, “Telomeres are repetitive DNA sequences at the ends of chromosomes which act as protective caps” (Rehman, 2014). When cells divide during mitosis, the chromosomes duplicate in order to ensure that both “daughter” cells receive the same amount of DNA. The telomeres protect the chromosomes during this process to......

...Franco, Reina L. Mrs. Luningning O. Marcelino BSN – 4B, B1 Ageism - also called age discrimination is stereotyping of and discrimination against individuals or groups because of their age. It is a set of beliefs, attitudes, norms, and values used to justify age based prejudice, discrimination, and subordination.1 Gerontology - is the study of the social, psychological and biological aspects of aging. It is distinguished from geriatrics, which is the branch of medicine that studies the diseases of the elderly.2 Geriatric Nursing - Nursing care of the aged patient given in the home, the hospital, or special institutions such as nursing homes, psychiatric institutions, etc.3 Issues Facing the Elderly Being old can mean being sick, poor, hungry and depressed, even in developed nations like Australia. What are the issues? In Australia, the ‘elderly’ is generally a reference to people over the age of 65. Lots of over 65ers lead healthy and empowered lives, and many are involved in community volunteering. But for the elderly, health can be a big concern. Their bodies are more susceptible to illness, they may be physically frail, and many are on medications which are costly and ongoing. An elderly person who is able to fund their own retirement is called a retiree. This means they had a job that paid them enough superannuation. Someone who is unable to fund their own retirement, and is paid welfare money by the government is called a pensioner.......
