Longevity research Essay Example for Free

Longevity research Essay Today, a great amount of people have learned to enjoy life once again as a senior in the community. This would speak of those in the 70’s and beyond. Life expectancy for Americans, which was a mere 49 years in 1900, has now increased to around 76 years. This we can say is due to improvements in health care, nutrition, and the overall standard of living. Not only are people living longer, but they are becoming more active in their older age, relative to elderly of the past. More older Americans are able carry out their own â€Å"instrumental activities of daily living† (Hodes 2003) As such, the desire for life has grown and billions have been poured into longevity research, an undertaking meant to discover ways and means to extend life. A vast motivation in science has been well-funded to discover how to keep man alive longer, with its aim toward more and more years. (Douglas 2006) There are concerns however one must view in light of this, namely, will a society with many living over a hundred years be actually as beautiful as it seems to present? The first concern would be the quality of life given that although the body may be kept health, the brain will be aging. Surely, the mind at the age of 110 is not as lucid as that of one at the age of 60. There are many diseases that correlate with the aging brain, but let us use the more common Alzheimer’s disease as an example. This is a devastating condition that has been seen to have a profound impact on individuals, families, the health care system, and society as a whole. Demographic studies suggest that if the current trends maintain themselves, the annual number of incident cases of this disease will begin a sharp increase in the year 2030 thereabouts. (Alzheimer’s association 2009) This will be a time that people born between 1946 and 1964 will all be over 65 years. Studies further show that by the year 2050, the number of Americans with the disease could double. Imagine these implications. It’s true that people live longer, but then what quality of life can one have if he lives 20 years more but has lost memory of his family and friends. This disease accounts for around 50-50% of cases of dementia. With increase longevity, there will be a large increase in the prevalence of the disease as people will be living to be older. It can be such difficulty to the individual to live in a condition where for years he is grasping at memories that he cannot recall. It’s an incredible burden to the family as well, as they will now be responsible for more elderly, living longer lives, incapable of self care, and maybe even incapable of recognizing kin. Imagine a scenario where a parent is 110 years old, their child being 85 and their grandchild at 60, how would it be feasible for the turn of care to pass from parent to child in such a scenario where all are classifiable as aged. A second concern is that apart from the aging mind, there is also the aging body. It is true that the individual will be living long, but then there are multitudes of risks that will accompany this. The wear and tear from all the years will now set in as he will now be more prone to multitudes of disease as years go by. Sicknesses like arthritis of the joints, a heart attack, stokes, cataracts, diabetes and many more will all now be factors that come into play. Even worse, should the person gain a long-playing debilitating condition, one with no cure such as the case of Alzheimer’s previously mentioned, then again what kind of quality of life can he sustain? Let’s take a stroke for example. Currently, a stroke is the third leading cause of death in the United States. Statistics show that over 143,579 people die each year in the United States from this condition. Now in terms of long term disability, stroke is the leading cause as people may live on with their life span after a completed stroke. Furthermore, having a stroke does not mean that a person cannot have another one to further cause disability. Now, it is seen that nearly three-quarters of all strokes occur in people over the age of 65. It is also noted that the risk of having a stroke more than doubles each decade after the age of 55. (Internet Stroke Center 2009) This is not even accounting for those who go through strokes at a young age. Now, given this data, imagine the risk for one who is to live until 120 years old. Imagine if a large bulk of population were to live this long, then the worldwide prevalence of stroke survivors would be high. After a stroke, it is very possible for one to lose control of speech, of movement in half a body, of mobility, and sometimes even requiring full time nursing care. The implications on a person and a family would be immense. Given that strokes occur generally in people over 65, imagine having one at 70 and then living for 40 more years. How would one survive that lone without the capacity to communicate. It’s true that one can live with the heart beating, but the question is in terms of quality of life. Another concern that also affects health will be the incidence of depression. A longer life for one spouse would mean having to live through the death of loved ones. Longevity increases the number of years one would live past the death of a spouse and family. Studies can increase life but imagine a scenario where a parent has to live past his spouse children and grandchildren. Again, the concern regarding quality of life comes in play is emotional makeup is indeed a very important aspect of human life. Rebecca Utz, a sociologist at ISR stated: While only about 6 percent of widowed persons had serious financial problems since their spouse died, 63 percent reported less income and 34 percent said their financial strain increased significantly after they were widowed. The negative economic consequences are even more pronounced for women than they are for men, and the declines are lasting, not a temporary drop associated with funeral expenses or estate planning. (About. com 2009) This itself is proof of how one’s death can affect an individual, not only in terms of health and emotion, but in terms of capability to function as well. Increasing longevity means increasing the chances that people will outlive one, or even more spouses, and have to deal with many deaths for many years. Depression rates will increase as a consequence of spouses living well past their mates, their children and maybe even their grandchildren. A study conducted showed that eighty-four (24%) of 350 widows and widowers met criteria for depressive episodes at 2 months, 72 (23%) of 308 did so at 7 months, and 46 (16%) of 286 did so at 13 months, further supporting this claim that depression and emotional consequences of too much longevity should be of concern. (Zisook, S Shuchter, S. 1991) A fourth point that should raise concern for biologic implications for longevity revolve around care for the elderly. Today, families turn to nursing homes and assisted living to give the elderly the care and attention they need. The alarming factor now revolves around what actual care they are receiving in these places, as a congressional report made by CBS news correspondent Bill Whitaker previously stated that around 1,600 U. S. nursing homes, nearly one-third of all in total, have been cited for abuse. These reported abuses were of various types, spanning from physical, sexual and verbal. All abuse in all these forms is on the rise. The report further noted that that more than twice as many nursing homes were cited for abuse in 2000 than in 1996. It was further seen that in 1,601 nursing homes , around 1 in 10 abuse citations were made in serious incidents. By serious, it was meant that they either put residents at great risk of harm, injured them or killed them. (CBS news 2001) Imagine how greatly the health of these poor elderly could be affected by increased longevity. Already at this current time with our elderly, society is unable to provide adequate care for them, and resorting to nursing homes and various assisted living environments that have led to elderly abuse. What more an increase can be expected if people were to live into the hundreds. The population would have a drastic increase in the aged, thus increasing the burden on society to care for them. If at this current day and age, society already is unable to manage the abuse problem, then the health implications of longevity are grave in that they will aggravate the abuse by increasing the number of elderly left alone. Investigators have further said that many violations are neither detected nor reported, which leads officials to conclude that the problem is even underestimated. Surely, if society cannot currently manage the elderly and provide a good, healthy and safe environment for them, then there is no way that society can do so after a further increase in the aged that longevity research will bring. My fifth and final concern regarding longevity lies in the fact that it will now place a large amount of population that has needs to be fulfilled but cannot fulfill them on its own. Increasing longevity will increase the number of senior citizens and the number of non-working elderly dependent. The health concerns for this are immense, as the question that can now be raised is regarding who in society will provide for the health of these individuals who cannot earn a living for themselves. CDC research concerns states that the increased number of people with ages over 65 will potentially lead to increased health-care costs. The health-care cost per capita for persons from the age group over 65 years in the United States is three to five times greater than the cost for persons below that age. (CDC 2003) Imagine how this will increase if people were to live 20 years longer. Currently, the number of persons aged 65 years is expected to rise from around 35 million in 2000 to an estimated 71 million in 2030. Longevity will even increase this number. Eventually, as resources will decline, then there will not be enough economic support to support the aged, leading to substandard healthcare and health risks. There may not be enough to provide them with medical needs, particularly because the working population may be outnumbered by the dependent elderly non-working populous. As such, in conjunction with many other previously discussed claims, the promise of longevity, although seemingly tempting, may not exactly be as, wonderful as it seems to be.

Caffeine in Athletics Essays -- Nutrition Sports Health Essays

Caffeine in Athletics The world’s most popular drug is legal, inexpensive, and believed to amplify workouts. It supposedly motivates athletes and helps them stay alert and focused while also boosting physical endurance by twenty to fifty percent. This stimulant is found naturally in sixty-three plants and is consumed by eighty percent of Americans. This white, bitter, crystalline substance is known as caffeine, and is commonly consumed in efforts to enhance athletic ability (http://gopher1.bu.edu/COHIS/substance/caffeine/about.htm). Caffeine is a very popular stimulant among athletes because most believe that it provides energy, increases alertness, and quickens reaction time. When in beverage form, caffeine reaches all body tissues within five minutes of ingestion. However, peak blood levels are reached in thirty minutes. Therefore, many cyclists consume a cup of coffee half an hour before short races begin. Others drink a bottle of coke diluted with water during the last half of longer races (http://www.roble.net/marquis/caffeine). The use of caffeine is controversial in the sports world, because it is a stimulant. In fact, the UCI forbids drinking caffeine in large quantities prior to competitions. But, why is there such a desire amongst athletes to consume this drug? Are its results really that effective? To answer these questions one must investigate how caffeine works. How does it affect the body? The exact process by which it affects the body is unknown. It is suspected that caffeine affects the nervous system by altering the perception of effort and exciting the neurons responsible for contracting muscles. It may also be accountable for causing more fat and less... ...1.

Apes to Man (Reaction Paper) Essay

Introduction Planet of Life: Apes to Man is narrated by Stacy Keach, presented by Discovery Channel. A must see documentary regarding the Theory of Evolution. Originally produced for Discovery Channel, each episode covers a separate chapter in the biography of the world. This episode examines the evolution with the use of computer animation. The film talks about how apes like Lucy, who is known to be a three million year old ape that walked upright or with two legs and revolutionized or grew and changed into one of the modern men and women who populate the world in every continent, nation and city today. The first stage in evolution is walking upright or with two legs just like Lucy did. The second is having the ability to speak or make different kinds of sounds. This is the cause of the straightening of the spine which allows the neck to follow for them to be able to speak. Summary One hundred million years ago, dinosaurs walked the earth. They no longer exist today because of the asteroids that hit their home and eventually killed all of them. The earth, after some time, regained its life forces because some small creatures that got through the great tragedy that  put an end to the era of the dinosaurs. One of those creatures that survived were the purgatorious, one of earth’s oldest primates that may have evolved throughout the ages A new era of animals rose to the occasion to a new beginning and to starting a new kind of living amongst the changed world around them. One particular creature happened to explore and discover new things in its surroundings more advanced than others. In the late 18th century, Charles Darwin wrote a book called â€Å"Origin of Species†. The book was intriguing. People thought he was losing his mind because most men and women during his time were very religious and really close to God. They didn’t believe him until a team of French-American researchers in the year 1974 found evidences of early apes. But by that time I think Darwin’s unlikely friends and haters won’t be able to say it in front of him. The people who found Darwin’s inspirational evidence called it â€Å"Lucy†. Lucy is a 3 million year old ape and is the very first one to walk upright or with 2 legs because according to the researchers she had wide hips like humans do. Archeologists say Lucy walked like a modern pig mea chimpanzee and bonobo. After a few decades, Lucy got to the second stage of evolution. And that is having the ability to speak or make different kinds of sounds. This is the cause of the straightening of the spine which allows the neck to follow for them to be able to speak and the rest is history. What Lucy became is what all of us are now. Generalization Evolution has really helped and changed every individual for the better. It made us realize and understand how the real world worked in the early ages and how it affected all of us today. We are now where we belong and that gives everyone the chance and the blessings they deserve. Reflection Personally, I do not believe in this theory as per the teachings in the Bible. There is no contest to what the Bible says about us  being formed in the image of God. But, for arguments sake, and if I were to believe it, let me just say that Darwin may have misconstrued the facts or the things he has observed based on the physical and genetic similarities of man and apes. He based his findings on the fact that because apes were able to walk upright, we are their descendants and from other scientists’ findings on the similarities of man and apes from different eras. Other important human characteristics – such as a large and complex brain, the ability to make and use tools, and the capacity for language added to the basis for his theory. Early human fossils and archeological remains offer the most important clues about this ancient past. These remains include bones, tools and any other evidence left by earlier people. Usually, the remains were buried and preserved naturally.

Essay on Science and Relgion - 1232 Words

Science and Relgion Science and religion have not always peacefully coexisted. There have been many issues where scientific discovery and religious belief have clashed. Religion is based on ancient belief passed down through generations. As humans discovered more and more about themselves, they found that many of the things that religion told could not true. This caused an incredible crisis between the pious religious and the scientific world, especially in the Western world where Christianity dominated society, and where these scientific discoveries were being made. It was difficult for people at first to believe in God and at the same time except these new scientific findings that negated many things that religion had told them.†¦show more content†¦Unfortuently, the church didn’t agree with Galileo. Philosopher Benedict de Spinoza also wanted to avoid the conflict between church and religion and felt that everything in the Universe was God and therefore the scientific inquiry of the t ime was important for discovering God’s true nature. Blaise Pascal also sought to keep religion and science united. He tried to show that Christianity was not contrary to reason. These men were obviously ahead of there time in understanding that religion texts are not science books, and thus it is up to mankind to discover the mysteries of our universe. The church was not so ahead of its time and were quick to excommunicate these scientific men. Many of the students of science and wealthy Europeans who learned of the advancements began to give up their religious pursuits, feeling that these findings proved that God did not exist. This was not the intent of these scientists, whose philosophy was usually that since the study of science helps men, and that is good, God must look favorably upon these pursuits. This era in history sparked a tradition of scientists giving up belief in God, and of religious men giving up a belief in science. The scientists did not completely give up on God, and a new religion that was thought up by philosophers and scientists of the time of enlightenment was put into practice.
