Cellular Aging

There are various genetic changes that people can experience the ill effects of that will presumably never be finished unless we effectively mediate and genetic engineering the cutting edge to withstand these issues. Case in point, Cystic Fibrosis, a dynamic and risky sickness for which there is no known cure, could be totally cured and annihilated with the assistance of particular genetic engineering, so it can almost never aging effect humans.

To slow down the aging process, you can alter things in your everyday life, for example smoking which is an extrinsic factor. Dr. Milton Moore, a Houston-based dermatologist says

Humans are born already aging. There is know way to stop the process of getting older. As people age it is important that services and rescores are set up to

The elderly population is growing rapidly and now makes up greater than thirteen percent of the United States population. (APA, 1994). With such a record growth, there are different aspects to aging that are still being analyzed. Many may think of reaching late life as a rite of passage, but many face this time with a different view. Through the movie "UP', we are granted an opportunity into view the struggles of an elderly widowed man by the name of Mr. Fredrickson and the challenges in which he faces in his later life. The movie, takes one on a journey through his sorrows and his triumphs until he realizes what the true meaning of happiness is.

Humans undergo several stages during their lifetime including growth, development, reproduction and senescence. Senescence is defined as the deteriorative biological changes that organisms experience as they age eventually leading to death. These changes include low metabolism, a weak immune system, memory loss, poor vision and loss of hearing. Senescence begins in humans during their post-reproductive years. However, gerontology research has shown that individuals who reproduce late have longer life spans compared to individuals who reproduce early. Nonetheless, it does not indicate that senescence is inevitable. All organisms experience senescence,

The aging process in late adulthood is called senescence. People cannot stop the effects of aging but there are alternatives that can help ease the process. These measures are not always followed because people make poor life choices such as smoking. Aging adults will even spend millions of dollars trying to slow the process of aging. No matter how much money they spend aging will occur.

(1) The theory that best support my current views on aging is the Wear-and-Tear Theory. The theory is “the idea that changes associated with aging are the result of chance damage to the body that accumulate over time”. (2) As many of us know, the body is constantly renewing itself. The cells in you is constantly creating new ones to replace the old, just like a boat. You are constantly restoring all the parts, where the boat will basically be almost all new parts. I think our body is like a built boat, car, or even a house, you must keep repairing it. Some people would literally get a new body part. A blood transfusion, heart replacement and a leg replacement are some examples of the theory. But just like a used car, boat or house, we stop

However fifty years from now, I can guraentee that more than half of this class will be using some form of anti-aging cream and this is just another thing that society has influenced us to believe. As my favourite quote, Morrie comments about this misconception when he says that "[wishing you were younger reflects] [u]nfulfilled lives ... becauses if you've found meaning in your life, you don't want to go back. You want to move forward" (118). Think about it. Apart from the fact that you're close to death, is aging really that bad?

In order to better understand aging-associated diseases, it is first necessary to define what aging is. Aging is a complex, multifactorial process of harmful mutations in cells and tissues that are accumulated over time and result in an increased risk of disease and, eventually, death (Tosato, Zamboni, Ferrini, & Cesari, 2007, p. 401). Contrary to the belief that aging can be cured through medical advances, it is scientifically accepted that, while human life expectancy has increased, the human life span has remained largely unchanged for the past 100,000 years (Tosato et al., p. 401). Therefore, future developments in aging research ought to focus on addressing treatment and prevention of major aging-associated diseases that will

Aging is natural. Every species ages on Earth. Humans seem to be one of the rare species on Earth that works so adamantly against aging, rather than

The article Understanding the Odd Science of Aging, characterize aging as “a progressive, generalized impairment of functions, resulting in an increasing vulnerability to environmental challenges and a growing risk of diseases and death.” In the article many theories are mentioned relating to why humans age such as the somatic mutation theory, telomere loss theory, mitochondrial theory, altered proteins theory and waste accumulation theory. Though

Diet full of nutrients, like minerals and vitamins along with regular exercise, can delay the process of ageing. (Turner, 2003).

The way God created us as humans is a life cycle where eventually late adulthood comes with the biology of aging. Santrock (2013) describes five different theories of why humans age (p. 541). The evolutionary theory explains that aging is more of a natural selection process, and diseases occur in the elderly because they “would have been eliminated” if they were in younger people (Santrock, 2013, p.541). Cellular clock theory describes how cells get tired of dividing after they have been reproducing for so long (Santrock, 2013, p.541). Free-radical theory explains when “cells metabolize energy the by-products include unstable oxygen molecules known as free radicals” (Santrock, 2013, p.541). The unstable oxygen molecules can damage DNA and other structures inside the cell (Santrock, 2013, p.541). Mitochondrial theory describes how aging occurs because of the mitochondria essentially wearing out and becoming less efficient (Santrock, 2013, p.542). Mitochondria are the cell’s “power house,” and they convert energy inside the cell (Bailey, 2008). The last theory, hormonal stress theory, illustrates the effects of stress, especially long term stress, on aging (Santrock, 2013, p.542). Stress released hormones which depress the immune system making people more susceptible to disease (Santrock, 2013, p.542). There are many theories about why human’s age, and all of them may be true, but regardless aging is inevitable and so are its effects.

Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives

Causes of aging are very uncertain. Besides, there are several factors which predispose an individual to premature aging. Current theories suggest that this process occurs to due to cellular damage such as DNA oxidation by free radicals causing
