How We Can Live Longer Essay

2. The MSNBC webcast recounts different stories of the aging population in America. One of the cases mentioned in the web cast is Arden peters and his wife Maxine. The aging theory of wear and tear can be applied to the case of Arden peters who has lost his wife Maxine due to dementia and Parkinson’s. He himself became too weak to care for himself due to the process of aging (MSNBC, n.d). He reached a point where he required someone to care for him. His friend Warren DeWitt is taking care of him and previously helped him take care of his wife until she passed away (MSNBC, n.d). The theory of wear and tear is based on the notion that aging is caused by damages done at the cellular level over time (Hawkley, Berntson, Engeland, Marucha, 2005). The processes that could damage the cells could be sickness, radiation, and accumulation of toxic materials over time

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 advancement of medical science impacted greatly on our specie and resulted in improvised life expectancy. Though progression of medical science brings cure for unlimited eternal illnesses it doesn’t however bring any remedy for the havocs caused by aging on our bodies. There

Atul Gawande in his book Being Mortal said “We are all aging from the day we are born” and aging brings death. But due to improvement in science and technology, the life expectancy has increased over the years and lots of diseases have been eradicated and symptoms controlled to prolong life. Despite these advancements, we can delay the death but cannot stop the damage. As these damages accumulate, there comes a time when one more damage shuts down the whole system bringing death to the whole organism. Gawande talks about diseases that affect the elderly and mentions that there is a shortage of geriatricians in united states which is affecting the access to care. He also mentions that it's not just worn and tear that causes aging or the genetically

Since the beginning of human history, emperors, conquistadors, alchemists, and many curious and powerful individuals have been in a fruitless search for a chance to transcend the realm of mortals and achieve immortality. Even now, at the dawn of the 21st century, the desire for immortality is still prevalent in our society today. However, while the dream for eternal life is still alive, the search for immortality is no longer just driven by power and greed, but for the universal gain of humanity – to solve many social and economical reasons that result from the current imperfect prolongation of life. Modern biogerontologists, people who study ageing, are determined to uncover the secrets of

With no disease or illnesses, humans can expand the length of life. Humans are beginning to live longer and longer because of modern day medical science. With genetic engineering, it could make our lives on earth even longer. “If we want to find the genes that help us remain physically active as we age, the genes that will allow us to play tennis when we’re 70 similar to when we were 40, we have to look beyond longevity as the sole criteria,” notes Tissenbaum, a professor of molecular biology. If scientist take genes that give us more physical activity when were young then when people become older their live a more physical lifestyle. Many individuals have a disease that holds them back in life from living a long life, but with the ability to genetically change that people would be able to live a longer healthier life.

For as long as humans have been able to develop societies and inquire about the world, people have been attempting to find ways to prolong life. The early alchemists searched for the ever elusive philosopher’s stone, while the Spanish Conquistadores traveled to distant lands in hopes to find the “Fountain of Youth.” Even today, we continue to search for the “elixir” of life. Currently, researchers are using modern science to find a way to extend our telomeres and allow our cells to regenerate, thus enabling us to live longer. Unfortunately, even with our advancements in science and medicine along with centuries of attempts, human mortality is one thing we haven’t been able to change. No matter how much we try and get rid of that fact of life, it remains a guarantee. Our greatest flaw as

Over years, longevity increases with the help of medicine and medical treatments. However, society haven’t planned for this yet. This is creating many problems to elderly themselves and people who are responsible to take care of them. This process of an aging society occur in every places around the world, specifically United States in this essay.

People these days are living longer and longer life’s then previous generations. There are many factors that come into with life expectancy and many things that contribute to it. Past generations have not had the resources of today’s 21st century. The 21st century has been a big ball of evolution for health and living factors.

Scientists See Aging Cured,” explains how and why life expectancies will increase in the future. The author, Kate Kelland, references Aubrey De Grey’s predictions on aging, which is that there may be a large amount of medical control over it in the near future, with people going to their doctors for techniques such as gene therapies, stem cell therapies, and immune system stimulation to keep them healthier. De Grey says that age can be controlled better by repairing molecular and cellular damage before it becomes too harmful. The author explains how longer lifespans will mostly be a result of better overall

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.

According to theory of aging, free radical interferes in this case. Aging is the apparently unavoidable decrease in physiologic function that happens after some time. At least four main theories of aging have been discussed that imply to clarify much or majority of the reason of biological aging:

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

Also spelled as ageing, this is generally the process of becoming old. It is the in a way the opposite of immortality. In a broader aspect, it may occur to single cells in an organism also called cellular senescence or the population of a species, known as population ageing. This process primarily affects human beings and fungi. In humans, it signifies the accumulation of various changes which occur over time. The changes include physical, social and psychological changes.

To maintain a longer life span the body must be taken care of and well oriented in facts about
