How to live longer?
An analysis of the impact food consumption and healthcare may have on life expectancy.

Econ413
SP2011

Introduction
Life expectancy is important not only to individuals but also to the nation. To individuals, longer life expectancy gives people more time in their lives to do things they want and gives them opportunity to see their children and grandchildren grow up. To the nation, studying life expectancy helps the government plan for pension benefits and contributions. I want to analyze the impact of food consumption on life expectancy because today people care about eating healthier and America’s eating habit has been criticized for the consumption of too much unhealthy food. In order to measure the country’s eating habits, I used data over the past 40 years that includes annual meat consumption, fish consumption, milk consumption, fruits and vegetable consumption and etc. I will analyze the life expectancy over 1970-2008 and the corresponding food consumptions over that time period.
In addition to eating habits, I believe that the nation’s healthcare spending and GDP are important determinants of life expectancy. Excluding them will result in a biased model. Therefore, I also included healthcare and GDP as independent variables in my analysis.
Prior Research and Theory In the past few years, life expectancy and its determinants have been widely discussed in economics. In the U.S., life expectancy rapidly increased in the past century and led to a rapid aging of the American population (Shrestha 2006). According to Munnell (2004), the analysis of life expectancy is complex and the range of determinants is wide. In his research, he only reviewed some of the most likely factors. One of the major factors is National GDP, because a richer a country has more resources to dedicate to education, medical care, and other goods and services…...

How to Live a Healthy Lifestyle

...How to Live a Healthy Lifestyle Want to get out of your potato lifestyle? All you have to do is follow a few simple steps and you're on your way! Firstly, Healthy food is essential; you can say that if you eat healthily, you are healthy. If you're just starting to have a healthy lifestyle, you probably don't know healthy food.

How We Ought to Live

...How we ought to live: Role of Religion and Government Abstract When one looks beyond the fundamental questions about life, it is pretty obvious that “how we ought to live?” follows whatever conclusion one reaches about their existence. This is an attempt to answer questions like: How shall we live? What shall we live for, if anything? How can we decide right from wrong? I look at the roles Religion and Government in showing us how we ought to live. When one looks beyond the fundamental questions about life, it is pretty obvious that “how we ought to live?” follows whatever conclusion one reaches about their existence. This is an attempt to answer questions like: How shall we live? What shall we live for, if anything? How can we decide right from wrong? Without requiring us to rely on blind faith alone, while using lessons from faith and rational thoughts. History Socrates (469-339 BC) used what we know today as dialectic way of answering Philosophical questions about life. This involved asking and answering probing questions in order to arrive at something that could be considered true. Unfortunately he was put to death for failing to acknowledge the gods that the city acknowledged and for introducing new deities. Aristotle (384-322 BC) thought that human fulfillment came as we order our lives around developing and expressing moral and intellectual virtues, such as courage, wisdom, generosity, and understanding. In order to do this, we must be mentally active. That...

How Should I Live

...How Should I Live? With each decision, we constantly ask ourselves, “Is this the right decision?” Sooner or later, we are all presented with the task to choose between what is right and what is easy. In one of my favorite novel series, Harry Potter, Albus Dumbledore says to Harry, “It is our choices, Harry, that show what we truly are, far more than our abilities.” (Rowling 1998, 219) This is true. Our decisions in life, our struggles, selections, and choices, are the bindings to our stories; ultimately holding together what makes us who we are, just as Dumbledore said. How should we live our lives? It is not a question that can be simply stated in a few words. One word out of the posed question is the main subject- “live”. What does it mean to truly live and what is the best way to do it? I think it is a mixture of many things. However, out of many lifestyles that involve moral behavior, I think the life of an altruist is an extremely honorable one, and it is one by which I want to model my life. In order to do good, one must know evil. So, what is evil? What makes good people do bad things? According to Philip Zimbardo, “evil consists in intentionally behaving in ways that harm, abuse, demean, dehumanize, or destroy innocent others -- or using one’s authority and systemic power to encourage or permit others to do so on your behalf” (Zimbardo 2007, 5). Throughout history, we have seen multiple examples of evil acts; from the Rwandan Genocide to Abu Ghraib to the......

How Is History Ever Present in Black Women’s Lives?

...Lau, Cheuk Hak AFAS 342-03 2013/11/30 How is history ever present in black women’s lives? 'When I reflect on Black women and images, the first thing that enters my mind is the portrayal of them through media images as self-hating, angry, miserable, and vindictive. All of those characterizations are fictitious and derive from Western America’s foundation of White supremacy, as the Honorable Minister Louis Farrakhan has so clearly demonstrated and proven.' —Dr. Ava Muhammad, attorney and Nation of Islam student minister The lives of black women in the early centuries were always tough. They were frequently the victims of sexual abuse and domestic violence. After Columbus first discovered America, Queen Isabella of Spain saw an opportunity to make a huge profit by sea trading. Her men bought black people in Africa, and sailed to America. People in America bought black people and put them all into farms, mines, and other places to do hard work. This was called triangular trade, and this is how black people first got into America. Whites treated black people like animals; they gave them the worst food, minimal breaks, and the worst dwellings. Black people had absolutely no rights back then. They were property of their owners. Most of the black women became slave girls. After they were bought by their masters, they became the easiest target for sexual harassment from their white masters. Almost every black woman had been sexual violated. For example, we have read a......

How to Live the Best Life You Can

...HOW TO LIVE THE BEST LIFE YOU CAN Crystel Santos 1. Start off by looking at yourself. Not in comparison to anyone else, but just look at yourself. Ask yourself these questions. * Who am I? * Where do I currently stand in my life? * What role do I play in others’ lives? (Sister, mother, friend, role model, teacher, partner, etc..) * Am I living to my fullest potential? * Am I happy? Fulfilled? At peace? * Why, or why not? 2.One huge mistake people make in their lives is sheltering themselves from pain. Hiding from the truth. Denying reality. DEATH exists. Become at peace with that. MURDERS and RAPE and DISEASES happen. Accept it. Once you face the facts that life isn't all rainbows and butterflies, you will be more prepared to handle tough situations, and you won't take disappointment as such a shock. 3.Determine which people in your life are actually worth your care. Eliminate all the fake friends and the users from your list, and list only those who make you feel happy when you're around them. Now make an effort to spend more time around those people, and less time around the people who do no good for you or your life. It's okay to be a little selfish in this sense every once in a while. Just be sure you give back an equal amount to what you take (and that doesn't only mean physical things, but emotional needs, as well). 4.Look on the dark side. Yes, this isn't a typo, the DARK side. Because often times, when......

How to Live a Sustainable Life

...How to live a sustainable life Summery In “Sustainable Living at Home in Australia” Linda Cockburn tells us about how she and her family moved and lived in their backyard for 6 months, because they wanted to appreciate life more and they wanted to learn for good, that material goods isn’t the only thing in life. In the 6 months they lived in the backyard they used the yard and animals for food and power. They drank the rainwater and they used the sun for energy. Linda Cockburn asserts that they learned a lot during that period. For example they learned to mix their own shampoo, and make their own toilet paper. After the course where the family lived outside, Linda Cockburn published her book “Living The Good Life”, which is about how the family discovered things they never knew before, and how much happier they became. On the top of the event a lot of people have sent Linda Cockburn praise and said that the book has helped them a lot. Outline All of the three texts are about how to live a sustainable life, but it is different whom the texts are written to, and they tackle the subject in different ways. The first text questions, how necessary it is to use electronic devices and consumerism, this much, in our everyday. So many people are addicted to their phones, and so many people can’t go a day without buying anything. It’s only 50 years ago that people barely knew about these things.

How Technology Has Affected Our Lives

...How Technology has Affected Our Lives Technology has certainly changed the lives of many people in today’s world. According to several reviews, as well as several books written by Nicholas Carr tend to point us in the direction of the technology not being such a good thing. While there are many forms of technology that are used for many different things such as: digital TV, social networking, cellular phones, notebooks, laptops, personal computers and the list goes on are they taking us away from the realities of life? Many sources or authors have their versions of how the different technology has made improvements in our lives; as well as how they are making us think and do a lot less than we used to. The internet makes getting information on any subject so easy for us that sometimes we tend not to do the work, or research that is needed to fully understand what we are doing; instead we follow the instructions and if we need it again we go through the same process without ever learning how to complete the task. This is just the beginning of how technology changes our lives and perhaps we get things done, but are we really learning? This is the question that we hope to answer along the way. There are many ways in which technology has in fact changed lives; the first concern that will be addressed is the way in which technology mainly electronic media has caused changes to occur. When we think of electronic media for this purpose we will focus on television,......

How to Live a Happy Marriage

...People are happy to be together, to share opinions, to spend time together, to make plans, which is inherent in their attitudes to each other. Happy marriages are tested, like others, by time, material difficulties, hardships, deteriorating health, fluctuations of mood, identity development, and the like. Happy marriages, unlike others, never ruin fundamentals of relationship: commitment is so deep that no difficulty can destroy it, since both spouses know how to help and support each other. Happy marriages cherish happy memories, and they cannot destroy these memories when one of the spouses has a temporary temptation to experience something new. On the contrary, happy marriages are full of wisdom, consensus, and their happiness is rooted in a unique feeling of freedom that ties up to a happy marriage experience more than anything else. They cultivate universal love, which is care, understanding, and tolerance to human weaknesses. Happy marriages are built by people who worship communication, interaction, and cannot live without sharing all they have in their hearts and souls. There is no couple that would not like to create a happy marriage. Only very few families can build long-term relationships that stick to happiness even under unfavorable circumstances. I have talked to married people who are happy in their own way. They feel the aura of happiness and advise others to be tolerant. A happy marriage is an ideal construct that is like a dream that cannot be......

How to Live a Happy Life

...January 14, 2013 How to Live a Happy Life I once read from the very popular Reader’s Digest that being happy can add seven up to ten more years in your life. From that time on, I have developed my own guide to a happy life. Although we are never free from troubles, we can always maximize our happiness. Well, there are so many articles on the internet, magazines and books presenting thousands of ways to be happy and reading all those can sometimes be tiring. To spare you from that, I have narrowed it down to four simple and general rules. So if you want to live those ten more years, all you’ve got to do is listen and pay attention. First on my list is to appreciate the little things like the sunshine or the rain; the leaves and the flowers; a nice cup of coffee or tea; and most importantly, yourself. For it is when we appreciate these little things, we become contented and eventually learn to become more grateful of the bigger things life has to offer us. Be thankful like a child and you’ll be surprised of the many great things the world can show you. Now, try to remember what you felt the first time your parents told you you’re having a trip to this really cool place. You were excited and that even made your spirits high. It’s that same feeling when you try something new. So, get excited and do something that can get you thrilled. Go out, explore out of the ordinary stuff, meet new people and have fun. Travelling will never fail you; getting lost can sometimes help......

How Collectivism Would Affect Our Lives

...How Collectivism Would Affect Our Lives The way a person perceives her/himself in relation to the surrounding human environment affects one’s emotional world. Collectivistic cultures emphasize the fundamental relatedness of individuals to each other; they tend to value attending to others, fitting in, and harmonious interdependence with them. Thus the self in collectivistic cultures is interdependent, and the individual is focused predominantly on his or her relationship with ingroup members or with the ingroup as a whole. In collectivistic cultures, emotions are experienced out of relationships. They reflect the outer, rather than the inner world and are therefore taken as objective: it is assumed that all people experience the same emotion in a given social situation. In collectivistic cultures such as China, the rules regarding emotions are rather loose: there are no strict expectations about how one should generally feel. However, the display rules are much tighter: there are certain expectations about the way one should show one's feelings in a given context. Culture affects the subjective well being. Well being includes both general life satisfaction and the relative balance of positive affect verses negative effect in daily life. Culture directs the attention to different sources of information for making the life satisfaction judgments, thus affecting subjective well being appraisal. A central theme of collectivism as a cultural syndrome is that relationships with......

How Do Adults Perceive That Significant Others in Their Lives

...‘How do adults perceive that significant others in their lives (i.e. people who are or have been important to them) have affected their development?’ Abstract John Bowlby’s theory of attachment asserts that in childhood attachments are formed between the infant and the caregiver. It also asserts that these attachments form the basis of adult relationships. This qualitative thematic analysis of an interview with Chloe attempts to show how early attachments form a framework of later development. This study shows some support for Bowlby’s theory of the continuity of attachment behaviour but also shows that the nature of attachments can change throughout life in particular due to adult relationships and life experience. Introduction The field of developmental psychology is concerned with understanding how our mental outlook can change over the course of a lifetime. It considers both the effects of cultural and environmental factors and the internal motivations of the individual. One of the main area of research is understanding the degree of continuity in how behaviour is formed and to what degree it can be influenced by past experience. In the area of human relationships, Attachment theory (as cited in Wood et al., 2007) explores how relationships develop. Bowlby (as cited in Wood et al., 2007) proposed that we have a basic biological drive to form an attachment to a ‘mother figure’ at birth. The nature of the attachment gives rise to a ‘internal working model’ in...

How Technology Impacts Our Lives

...Technology has had a big impact on the way people lead their everyday lives. The cell phone, I believe, has had the biggest impact on the way we navigate through our daily tasks. There are an estimated 180 million smart phone users in the United States today. Personal relationships, the hours spent working away from the office, and how people pass time are all very different than they were 30 years ago. Personal relationships, in my opinion, have had the hardest hit when it comes to the advancement of smart phones both bad and good. People take less time out of their day to place a phone call to a loved one and send a text message instead. Dating is also driven by applications that we can download to our smartphone. A person can decide whether or not they want to go on a date with someone based on a profile picture. Applications such as Face time and Skype, on the other hand, have opened a door to a more convenient way to communicate with someone that may be too far away to go visit. With the advancement of cell phones, it has become harder for people to not work while off the clock. Email, videoconference applications, and simply being able to make a phone call from anywhere have given all of us access to our work any time of day that we want. This advancement has, however, has created pathways for new moms. This allows mom to stay at home and care for her family while allowing her to access her work and continue down her career path.
