The average life expectancy as of 2011 is about 78 years old, which we would consider as a fairly long, well lived life. However, an incredible woman named Hendrikje van Andel-Schnipper died at the age of 115 in 2005. van Andel-Schnipper was born in the year 1890, a time when life expectancy was between the ages of 40-50 years old. van Andel-Schnipper more than doubled that life expectancy and proved the impossible was possible! Miracles such as that of van Andel-Schnipper, are amazing, wondrous and mind boggling to scientists, but what they found in van Andel-Schnipper’s body was even more so. During the study conducted by researched based at the VU University Medical Center of Amsterdam, they wanted to find out as much as possible about her to possibly obtain a better understanding of how she aged so well. In particular, the researchers were interested in looking out how mutations in somatic cells occur as people age. During the study, researchers found 450 somatic cell mutations in her white blood cells. These …show more content…
As such, somatic mutations lead to ge- notypic and possibly phenotypic heterogeneity within and between tissues, and they may compromise growth or lead to a growth ad- vantage (Frank 2010). Because somatic mutations often occur during cell division, frequently dividing cell types are more prone to acquire somatic mutations than tissues that rarely divide (Youssoufian and Pyeritz 2002). Consequently, frequently dividing cell types, i.e., epithelial cells, hematopoietic cells, and male germ cells are vul- nerable to somatic mutations that may lead to tumor development or other diseases and disorders. Therefore, most studies regarding somatic mutations have been attempts to discover mechanisms leading to cancer and disease (Youssoufian and Pyeritz 2002; Erickson 2010; Hanahan and Weinberg

Charles Albert Dutch Ruppersberger is one of the congressman for the state of Maryland in Baltimore County, specifically the second district. Born in the city of Baltimore Maryland on January 31, 1946, Ruppersberger has made many contributions to the area of which my family and I live. Growing up, Ruppersberger lived the life of a typical student in America. He attended Baltimore City College where he received his high school diploma, while later furthering his education to the University of Maryland College Park; there he earned his B.A. Finally Ruppersberger obtained his goal of earning a Juris Doctorate from the University Of Baltimore School Of Law. Along with receiving a higher education Ruppersberger loved to play lacrosse. All of the schooling that Ruppersberger went through prepared for him for the role that he currently plays in our community.
Cornelius Vanderbilt was an enigma, an insanely complex person with conflicting personalities. He started his career opposing the idea of monopolies, a champion for individualism and free markets, but ended his career by building the very things he initially opposed, monopolies. He was a shrewd businessman, who only cared for himself, but during the civil war,he was a national patriot. He was willing to donate his ship, The Vanderbilt (approximately worth over 1 million dollars at that time, a significant amount of his fortune), to the Union Army for $1. During the civil war, he sided with the North, but after it, he married a loyal Confederate woman, and bailed out Jefferson Davis. He also donated 1 million dollars to the Central University in Tennessee, which was later named after him. For all his complex personalities, it was without a doubt that "The Commodore", a moniker he earned for his great success in the shipping industry, that he was one of the First Titan of the American Industrial Revolution. He was a strong proponent of Capitalism and gave the nation what it needed most during its great time of change, cheap and efficient transportation. This is the story of the " Robber Baron", his rise, triumphs and defeats.

Somatic evolution is the accumulation of all the mutations in the cells of an organism throughout a lifespan. Understanding somatic evolution plays an important role in the science of aging and gives insight into the development of cancer (Boland, 2005). “The somatic mutation theory of aging posits that the accumulation of mutations in the genetic material of somatic cells as a function of time results in a decrease in cellular function” (Kennedy, 2011). In other words, as organisms progress through life their cells will ultimately begin to deteriorate due to changes in their genetic material.
During the Industrial Revolution of the Victorian Era, life expectancy was so low due to the lack of sanitation, working conditions, and less medical knowledge that we have now. At the time, the average age people were dying was at 35 years old (Lambert). The age, however, varied depending on where one lived. Normally, people who lived in cities died at a younger age than people who live in rural areas. The class that one was in also greatly impacted a person’s life span. It mainly impacted poor working-class communities, because of the poor conditions that came with being a member of that class (Wilde).
An ordinary human body contains approximately one trillion cells and precisely 46 chromosomes in each cell. However, the human body can be altered by a genetic mutation. Over the course of history, genetic mutations have had a large impact on the human race. They have brought harm to numerous amounts of people. Cancer, in particular, is one of the most lethal diseases. Cancer begins when a portion of DNA inside a chromosome is damaged, causing a cell to mutate. Then, the mutated cell reproduces multiple times and creates a tumor. Afterwards, cancer cells break off of the tumor, enter the bloodstream, and disperse throughout the body. If the cells break off, the tumor is considered malignant - this type of cancer is very difficult to cure. Many patients today stay optimistic for a medication to heal cancer. It is imperative to address a few of the causes and effects of cancer in order to gain a general knowledge of genetic mutations.
In today’s society, what was once said to be true and taken as fact regarding older people is no longer the whole story. As Laslett states, “At all times before the middle of the twentieth century and all over the globe the greater part of human life potential has been wasted, by people dying before their allotted time was up.” (1989a), and to a great extent a lot
The cancer cells from gene-mutation. Scientists now know some of the risk factors for lung cancer can cause certain changes in the DNA of lung cells. These changes can lead to not normal cell growth and, sometimes, cancer. DNA is the chemical in each of our cells that makes up our genes and how our cells function. People usually look like their parents because they are the source of our DNA. But DNA affects more than how we look; it also can affect our risk for developing certain diseases, including some kinds of cancer like lung cancer etc…Some people inherit DNA mutation from their parents that greatly increase their risk for developing certain cancers.
...of not only them but also other things. (Schulz 2005). Finally, in conclusion, gene mutations and alterations affect the body’s ability to control the rate of cell division, which therefore defines cancer the direct result of gene mutation. Cells affected by mutations are exposed to the reproduction into a tumour. Once the tumour expands in growth, more and more mutations occur in subsequent cell divisions and eventually become a dysplasia and instigates invasion into surrounding tissues. In simpler terms, the cancer is spread to other organs and parts of the body. Following this, metastasis occurs resulting in the cancer spreading through the person and/or animals blood stream and/or lymphatic systems and forms other colonies which thus secretes other harmful organelles, and also disrupts normal bodily function, and possibly leading to and eventuating in death.
As American society has evolved in the past 100 years and technology has increased and improved, so has the life expectancy for individuals. Currently, females can expect to live for 81 years on average, while males can expect to live for 75 years, giving an average life expectancy of 78.3 years (Santrock, 2013, p.536). According to Santrock (2013), “since 1900, improvements in medicine, nutrition, exercise, and lifestyle have increased our life expectancy an average of 30 additional years,” but another important factor is the decreasing infant mortality, allowing a larger population of people, including older adults (p.536). Making good choices in diet, regular exercise, avoiding drugs and alcohol, along with getting enough sleep and maintaining a low and healthy stress level can all increase life expectancy. Relationships, emotional well-being, and having purpose all also play an important role in determining how long an individual will live. As people are living longer, more ...
In a research conducted by the American Academy of Family Physicians, patients with this disorder trait have a normal life expectancy provided to live a health live style – health eating regular exercises. However, those with the more severe form of the disease (beta thalassemia major), on average live 17 years and generally die before their thirtieth birthday.
Hans Christian Oersted was born in Rudkobing on August 14, 1777 to Soren Christian Oersted and Karen Hermansen. His father was an apothecary and did not have the time to properly raise Oersted or his brother so they were raised by a German wigmaker. When he turned eleven, he went to work for his father at his pharmacy, where his first interest in science began. Without any prior schooling, except what he learned informally through others, he passed the entrance exam to University of Copenhagen, where he graduated with honors. In 1806, he later became a professor of physics at the same university. Although he was both a Danish philosopher and physicist who made contributions to the scientific community including the isolation of aluminum, he is best known for his discovery that linked electricity and magnetism.
Human beings age and they have since the beginning of time, but it remains an unsolved mystery. This enigma has remained in the dark until the recent innovations technologies have shed some light on this elusive topic; cells are the key to figuring out why humans age. Aging seems to be a relatively simple process, but the more it is studied, it is evident that it is rather complex. There are a myriad of factors that contribute to aging, but none of them can single handedly answer the question of why humans age. This age long question is at the forefront of medical research. As a result, discoveries are frequently made, which contribute to the ever growing pool of knowledge. Perhaps in time, by researching this topic, the human lifespan will lengthen and the diseases that often plague the elderly can be prevented or subdued to a greater extent. Furthermore, human aging is proven to be closely linked with illnesses such as cancer, which is why so many world class scientists are pursuing this topic. Interestingly enough, there is no universal theory that is widely accepted by the scientific community; however, there are many theories that credibly explain the science behind aging. Aging is a subject that should be studied because it directly benefits many lives, and has tangible results.
Technology in terms of medicine has also increased the life expectancy of the average person. With new technological advancements in surgeries, medicines and treatments the average life expectancy is still on the increase. A recent study shows that the average life span for 2004 of a United States Citizen is 77.4 years old. This has increased significantly from 1900 where the average lifespan for a male was 48.2 and for the female 51.5. Thanks to technology we can now live longer.
