Internet privacy Essay Example | Topics and Well Written Essays - 750 words

Internet privacy - Essay Example People are encouraged to ensure timely update of their antiviruses and to be sure with what they click at any given instance. The widespread use of social media platforms has further aggravated the matter as personal information is made accessible to those within the social brackets thus increasing the chances of cyber crime. Internet privacy relates to the right of personal confidentiality on the storing as well as availing of information to third parties through the internet on specific issues. This is regarded as a subset of computer privacy in the ever growing information sector. The level of privacy in the internet can be divided into personally identifying information which refers to any information that is used in the recognition of given individual factors such as physical address or other personal bio-data and non-personal identifying information which excludes any personal information regarding an individual (Imparato, 2000). Countries all over the world as well as the United States of America are trying all workable methods that are aimed at ensuring total protection of personal information by maintaining their privacy (Frackman, Martin, & Ray, 2002). With the proliferation of social media, avoiding revealing sensitive data can be difficult making laws and government regulations necessary for maintaining privacy. One of the steps towards enhancing internet privacy is by encouraging people not to carelessly or mistakenly revealing personal information via the internet. One can easily made public their personal bio-data over the internet without being fully aware of it hence the need to be very careful when using the internet. One should make use of pseudonyms instead of using real names and actual personal information. The browsers used should not be in a position to leak out personal information or retain them for a longer period of time (Jakubiak,

Diffusion Across Biological Membranes Essay Example for Free

Diffusion Across Biological Membranes Essay From the cell simulation modal made, it has explained about the aspects of diffusion and indicator solution (chemical testing) to test for particular substances. From the observation made, iodine and glucose have greater concentration due to small molecular size and also they are monomers. It means their molecules are smaller. Thus, it diffused out to create a state of equilibrium. On the other hand, starch molecules did not move by diffusion across a membrane into or out of the cell due to the large molecular side. This is because many repeated glucose subunits are found in starch structure. Starch is a polymer. This is the reason why the water in the beaker or 1 inch dialysis tube did not turn dark blue as no starch molecules diffuse out. However, the liquid outside of cell was cloudy. When iodine indicator and Benedict’s test, tested for presence of iodine and glucose respectively, the colour change was not very distinctive. Hence, we came to a rationale that more time could have needed for glucose and iodine achieve diffusion as 1 hour was not enough to complete as perhaps molecules on one side of a membrane become trapped by binding to macromolecule. On the other hand, perhaps water in the beaker could have been too diluted so could not detect the presence of glucose and iodine using indicators. This process is termed as osmosis. In osmosis, molecules also travel from higher concentration to lower concentration. However, osmosis only occurs in water. Water molecules are polar and small enough to pass through the membrane. Therefore, from this experiment, we can understand that water is essential for cells survival. However, too much of water will result in hypotonic. ells is placed with a lower concentration, then osmotic pressure of the extracellular fluid is less than intracellular fluid. As a result, water flow into the cell causing it to swell and undergo lysis (burst). Likewise, if a cell is placed into a solution with higher osmotic concentration than the intracellular fluid such as salt solution. The osmotic pressure of the extracellular fluid will exceed that of the intracellular fluid casing the cell to shrink and crenate. Hence, it’s hypertonic. This explains why when a small dose of fertilizer can enhance plant growth but over fertilization can kill the plant. Fertilization has salt and salt dehydrates the cytoplasm in the cell and would dry up making the cells shrivel up and die. Iodine indicators and Benedict’s solution proved that when a substance reacts with its indicator solution, a reaction will occur and cause a colour change. In this case, iodine test used to test for the presence of iodine in the solution and Benedict’s solution is use to detect glucose. It is important for Benedict’s solution to be heated as it’s a way to prove that it is the mixing of the two that creates the bright orange colour. If the benedict’s solutions were to be heated separately or the solution to be heated there will not be any results produced to test the presence of glucose. The indicator solution will react only if the substance is meant for is present, then it will react. Else there would not be any changes to observe. Indicators come in handy when dealing with unknown samples of ingredients to prove what a substance is. A negative control is used yield a negative result. This is to ensure that all the reagents are pure and there is no contamination that will give a false result. Conclusion In conclusion, we can conclude that diffusion occur spontaneously and molecular size and charges matters when molecule pass thought cell membrane unless its molecular size is small and it’s a monomer diffusion will occur spontaneously. However, if the molecular size is big and it might also hinders the passage way for smaller molecules to diffuse to a higher concentration to lower concentration to bring it to an equilibrium state. We also concluded that cell should maintain a isotonic environment to conduct its activity smoothly else in hypertonic or hypotonic, it will burst or shrivel and eventually kills the cell. Therefore, diffusion and osmosis are types of passive transport and happens spontaneously.

The Gas Exchange And Transport

The Gas Exchange And Transport The changes in pulmonary ventilation and blood flow are actually regulated by the central nervous system through the respiratory and cardiovascular areas located in the brain. According to Sir Joseph Barcroft in 1934, exercise actually forces both cardiovascular and respiratory system to perform at a higher level of function. [1] This helps us to understand better how both respiratory and cardiovascular systems interact with each other to perform well. Gas Exchange and Transport Gaseous exchange occurs in the alveoli of the human lungs. Air in the alveolus has a higher partial pressure of oxygen compared to the blood in the pulmonary artery. Therefore, oxygen diffuses into the blood at capillary by dissolving in the moisture on the alveolar surface. On the other hand, air in the alveolus has a lower partial pressure of carbon dioxide compared to the blood in capillaries. Hence, the carbon dioxide diffuses from the blood capillary to alveolus to be exhaled out. [2] There are several factors which affect the gaseous exchange of carbon dioxide and oxygen between the blood capillaries and alveoli in the lungs. These factors are the surface area available for diffusion, the length of the diffusion pathway, and the hemoglobin concentration in the blood. At rest, not all the capillaries that surround the alveoli are open. During exercise, more alveoli and capillaries are opened which increase the surface area to allow a faster diffusion to occur. [1] During exercise, there is also movement of fluid from blood into the surrounding cells and tissues. This is termed hemoconcentration. This will increase the concentration of hemoglobin in blood by 5% to 10%. [1] The increase in body temperature that causes the person to sweat will reduce plasma volume. This will produce hemoconcentration as well. This is the reason why during exercise, gas transport per unit volume of blood flow increases. [1] Oxygen Dissociation Curve Respiratory system is responsible for the exchange of oxygen and carbon dioxide between our body and the environment. When inspiratory muscles contract, air rushes into the lungs due to the higher pressure of external environment. Air is forced out from the lungs to the environment during expiration when the pressure inside thoracic cavity becomes higher. [2] During exercises, active tissues such as skeletal muscles need more oxygen to generate ATP. [3] Therefore, they produce more carbon dioxide and the body temperature increase. This carbon dioxide will react with water in the tissue to form carbonic acid which increases acidity. Increase in the acidity of blood will reduce the affinity of hemoglobin to oxygen. As the result, more oxygen is released to these active tissues. [2] For example, during moderate exercises, skeletal muscles need more oxygen and they produce more carbon dioxide due to the work out. So, the pH is decreased causing the affinity of hemoglobin to oxygen reduce. Hemoglobin with a lower affinity to oxygen has oxygen dissociation curve which is further to the right. Body temperature which increases during exercise will cause the shifting of oxygen dissociation curve to the right as well. [5] According to Merle L. Foss and Steven J. Keteyian in their book, Physiological Basis for Exercise and Sport, the respiratory system change the rate and depth of ventilation to help regulate the hydrogen ion concentration of our body fluid. When body fluid pH decreases, for example, during exercises, ventilation increases to blow off carbon dioxide. When at rest, ventilation decreases to retain carbon dioxide in body fluid. [1] Ventilation changes during exercise Involuntary control of breathing is carried out by the breathing center in the medulla oblongata. [2] This breathing center consists of an inspiratory center and expiratory center. The partial pressure of carbon dioxide which also affects the pH of blood is the most important factor controlling the rate and depth of breathing. The chemoreceptors detect the changes in partial pressure of carbon dioxide of blood and cerebral spinal fluid. These chemoreceptors are the carotid bodies, the aortic bodies, and the medulla [1] that near the breathing center. During moderate exercises, there is a rapid increase in the partial pressure of carbon dioxide in the blood. This is due to the accumulation of lactic acid in muscles. The increase in the partial pressure of carbon dioxide stimulates the chemoreceptors to transmit impulses to the inspiratory center. Inspiratory center transmits impulses to diaphragm muscles and intercostal muscle for rate and depth breathing. [3] At the first few second after start the exercise, there is a rapid increase in the ventilation. This is due to the increase in the central command from cortex. The increase in the neural stimuli to medulla because of the activation of muscle or joint receptors may cause the hyperventilation as well. After that, the rapid ventilation start to achieve at steady state or it shows a slower rise. This is because chemoreceptors start to react to increase in the partial pressure of carbon dioxide and decrease in the pH of blood or cerebral spinal fluid. The ventilation continues to increase until the exercise is stop. [1] During normal breathing, a human adult inhales and exhales about 450cm ³ of air. This is known as tidal volume. During vigorous activity, tidal volume can increase up to 2000cm ³. [2] Oxygen uptake increases linearly as the work rate is increasing. However, above a certain work rate the oxygen uptake reaches a plateau. Thats mean there is a limiting factor to oxygen up take. [3] Structure of Human Heart Human heart consists of 4 chambers, left atrium, right atrium, left ventricle and right ventricle. Both the left and right ventricles have thicker muscular wall compare to left and right atria wall because ventricles need to contract strongly to pump blood out of the heart. Whereas, the wall of left ventricle is 3 to 4 times thicker to right ventricle because left ventricle need to pump blood to all parts of our body except lungs while right ventricle pump blood to lungs only. The intraventricular septum separate left and right side of the heart completely. Left atrium receives oxygenated blood from lungs via pulmonary vein while right atrium received deoxygenated blood from the body through vena cava. [7] [6] Control of Heart Beat Heartbeat is myogenic. This is because beating of the heart is started by cardiac muscles and not by external stimulation. Sino atrial node (SAN) which is also known as the pacemaker for the heart is responsible to originate excitation for starting the heartbeat. SAN have a high permeability to sodium ions. So, SAN cells are depolarized as sodium ions diffuse into these cells continuously. The depolarization will generate electrical impulse that transmitted out from SAN cells to produce contraction of heart. Atrial systole occurs when the wave of excitation is conducted from SAN to walls of both atria. The impulses that generate by SAN is then activates atrioventricular node (AVN). AVN then transmits the impulses to apex of the ventricles via bundle of his. From the apex, impulses are transmitted to ventricular muscles through purkinje fibers. This transmission causes ventricles to contract and hence pump blood into pulmonary artery and aorta. [2] SAN can be accelerated or slowed down by the autonomic nerve system, endocrine system and some other factors. The amount of blood return to heart actually can induce the increase in the stroke volume and cardiac output of the heart. During exercise, the working skeletal muscles contract strongly and quickly. As a result, a large amount of blood is return to the heart via vena cava. There is stretch receptors (baroreceptors) located within the wall of the vena cava. When large amount of blood return to the heart, the vena cava dilates and this stretches its wall, stimulated the stretch receptors there. The stretch receptors then generate impulses at high frequency to transmit to cardiac accelerator center in the medulla oblongata. The stimulated accelerator center then transmits impulses via the sympathetic nerves to induce a faster and stronger heartbeat. [1] According to Starling Law, the strength of the heartbeat is related to how much the cardiac muscles are stretched. Therefore, the more the volume of blood returned to the heart, the stronger the ventricle contracts. [4] Stroke volume increases due to the strong ventricular contraction, thus there is high blood pressure in carotid artery and aorta. Stretch receptors are stimulated and transmit impulses to cardiac inhibitory center to slow down heartbeat. This is to prevent the heart from beating too fast. [2] Distribution of Blood Flow At rest, majority of the cardiac output is distributed to the visceral organ, the heart and the brain. Only 20% of the total systemic flow is distributed to the muscles. [1] However, during exercise, more active skeletal muscles received a higher proportion of the cardiac output due to the redistribution of the blood flow. The metabolic active skeletal muscles will receive 85 to 90% of the total blood flow during maximal exercise. [1] The redistribution of the blood flow is caused by the vasoconstriction of the arterioles at visceral organs and non-working skeletal muscles which are less active metabolically during the progress of exercise. The vasodilation of the arterioles which supply blood to the active skeletal muscles is also the reason that causing the redistribution of the blood flow. [1] The vasoconstriction of the arterioles at non-active tissues in our body during exercises is due to the increase in both neural input and release of noradrenaline to the blood. On the other hand, the vasodilation of arterioles at active skeletal muscles during exercise is mainly due to initial reflex sympathetic nervous system response and chemical changes in the body. Those chemical changes include increase in temperature, partial pressure of carbon dioxide, hydrogen ions in plasma and blood, lactic acid level and decrease in the partial pressure of oxygen. The innermost layer of the arterial blood vessel will also release a vasodilation substance which is nitrous oxide to induce vasodilation of arterioles. [1] Blood Pressure Regulation Blood pressure is regulated by coordinating cardiac output and the diameter of the arteries. As cardiac output increases, blood pressure increases as well. Arterioles vasodilation lowers the blood pressure while arterioles vasoconstriction raises the blood pressure. The neurons from the vasomotor center in the medulla innervate the smooth muscles in all arterioles. [2] During exercises, there is increase in the cardiac output which raises blood pressure and stimulating the stretch receptors in the aortic arch and carotid sinuses. The stretch receptors then transmit impulses to the vasomotor center in the medulla. The vasomotor center then responds by causes the arterioles to vasodilate to decrease the blood pressure. It may cause the cardiac output to decrease also. [2] Blood pressure also affects by the partial pressure of carbon dioxide. During exercise, the increase in the partial pressure of carbon dioxide will stimulate the chemoreceptors located in the carotid bodies. The chemoreceptors then transmit the impulses to the vasomotor center in medulla that causes the arterioles to vasoconstrict. This can facilitate the carbon dioxide excretion as more blood can be transported to the lungs. [2] Conclusion After go through all the topics that we discussed above, we can conclude that all the adjustments make by respiratory and cardiovascular systems (cardiopulmonary) need to be controlled, coordinated and interact with one another well to operate at a higher level of function. Cardiopulmonary system is able to function efficiently because of the control of nervous system which involves both voluntary nervous system and involuntary nervous system. As both cardiovascular and respiratory systems are interconnected with each other, therefore, the stimulation of one area such as the increase in the partial pressure of carbon dioxide will affect both ventilation and blood flow. As a result, to study physiological changes during moderate exercise, we need to study both cardiovascular and respiratory systems to understand better how they work.

Black Thusday: The Crash :: essays research papers

In the roaring 1920s, the United States bathed in previously unheard of prosperity. Industry and agriculture alike profited from the thriving economy. The Federal Reserve Board (known as "the Fed") practiced a policy of easy money, and consumer conf idence was high. Average income grew steadily throughout the decade and production soared. Levels of investment grew to new heights. At year's end in 1925, the market value of all stocks totaled $27 billion. By early October of 1929, that number had g rown to $87 billion. However, the economy began to slow down in 1928, and the trend continued in 1929. Agricultural prices slipped, a result of production surpluses and a downturn in business activity. In July of 1928, the Federal Reserve Board, took n otice and hiked interest rates in an attempt to slow investment to a pace more appropriate to the economic decline. Despite this and other warning signs, patterns of investment continued much as they had in the mid-20s, giving littl e recognition to the e conomic slowdown. The stage was set for a major market correction. On October 24, 1929, dubbed Black Thursday, the stock market crashed. Prices began to decline early in the day, triggering a selling panic in the New York Stock Exchange (NYSE). When trading closed the Dow Jones Industrial Average had fallen 9 percent and 12,894,650 shares of stock had changed hands, smashing the previous record of 8,246,742. Despite the crash, reports remained optimistic. Major New York banks united to buy up $30 million worth of stock in efforts to stabilize the market, and president Herbert Hoover announced that recovery was expected. Hoover's claims had little merit; the situation became bleaker during the next week. October 29 broke the now four-day old NYSE record for number of transactions: 16,410,035 shares changed hands in total. The market dropped 17.3 percent, confirming, and cementing, the permanency of the crash. The coming months saw no recovery. The crash in the market spelled disaster for the national economy. Corporations with heavy investments faced a sudden and almost insurmountable shock to their assets. Investing froze. As a result, the national economy fell into an unprecedented period of depression. Import spending dropped from $4.399 billion in 1929 to only $1.323 billion by 1932. The same period saw a sharp drop in exports as well. National income slipped lower each year from 1929 to 1932, and did not return to pre-depression levels until World War II.

Effective and prefessioanl communication in nursing Essay

Today, nurses and midwives in their professional practice need to communicate in many different ways, maintain an open minded attitude that will allow for superior preparation in nursing assessments and in practice and provide person centred care. They are also required to demonstrate their capacity to think critically about issues, organise ideas logically, take action and reflect on that action to implement continuous improvement in future situations. Emotional intelligence is the foundation for reflective practice; therefore the aim of this paper is to outline the importance of having a clear and concise understanding of the skills mentioned and continuously expanding knowledge throughout studies and ensures this continues into and throughout a career in the health care domain. Verbal communication is the transmitted information from one to another, or to many, in the form of spoken words or written text (Hillege & Groome, 2007). However, there are many other options to transmit information if verbal communication does not benefit the situation. Non-verbal forms such as touch, facial expressions, posture, gait, gestures, sound and a person’s subjective data are also forms of communications which are vital to the medical scope. I feel strongly towards the importance of recognizing all areas of communication and believe non-verbal communication is helpful and can bare more truth despite what the verbal language indicates. Nurse-patient interaction is the pulse of nursing (American Society of Registered Nurses, 2007). Verbal communication is used extensively when providing care, however, when verbal transitions not clear due to language barriers, other avenues of gaining information must be sourced. Awareness of this in nursing practice, together with skilled perception to decipher and piece together a patient’s source of distress by acknowledging what messages the body is convening and what is being said and with that to treat the patient effectively. Lewis & Foley (2010) stated that there are many aspects to conducting a health assessment. Two of these are preparation and collecting data. I feel that the involvement in understanding and performing these assessments correctly is more complicated than I initially thought. The patient’s biographical data, subjective data  and the equipment needed for the nurse to collect such information must all be considered in preparation for the assessment to be precise, paramount and to maintain the person centeredness towards the patient’s own self values. Nurses and midwives need to show respect to the patient’s holistic health (Blackman, 2010). By applying this concept to my nursing practice, it will help me to develop an accurate health assessment. Person-Centered care sees that the patient plays an equal part in planning, developing and assessing their care plan to make sure it is concise with their needs (Dempsey, 2009). It involves considering the patients holistic health and social determinates and putting patients and their families at the center of all decisions. I feel that it is imperative that the patient feels secure and respected by the health care professionals that have instilled trust through their own emotional intelligence. Modern day demands of nursing depend on the skills of emotional intelligence which then achieves person centred care (American society of Registered Nursing, 2007). By applying these concepts in my daily nursing practice I am working towards gaining the most positive foundation for an individuals’ care to take place with positive outcomes. Stance and expression show sincerity towards a patient. Appearance, facial expressions, attitude, ability to listen and remain silent allowing the patient to talk openly indicate professionalism and show a nurses’ demeanor to the patient (Lewis & Foley, 2010). I feel that these are important skills to develop as a health care professional. It is critical as a nurse that we are aware of our non-verbal language and that it portrays a message that complements the verbal communication. Non-verbal interactions play a vital role in nurse-patient perceptions (Blackman, 2011). Displaying neutral expression is not incorrect, rather it can allow for appropriate expression inside the zone of helpfulness. When interacting with patients in the clinical scene I now know the importance of maintaining professional demeanor towards them. Lewis and Foley (2010) stated that through stages of life, consideration and opinion of one’s self is developed through a combination of others’ attitudes and the internalised understanding of ideal self. These factors can have positive or negative effects on the development and stability of self-concept. I feel  that it is important to recognise a persons’ sensitivity to influence on both the care giver and receivers end. Influences are ever changing depending on a person’s faith, socio-economical positioning, interpersonal relationships and emotional intelligence. Emotional intelligence has grown in popularity among nurses over the last two decades, generating interest both at a social and professional level (American Society of Registered Nurses, 2007). I, as a nurse, must have emotional intelligence in order to reflect it back on patients, thus stimulating their own positive self-concept and avoiding emotional down scale which could have otherwise caused them to suffer inadequate care. As nurses and midwives we must demonstrate confidence in understanding that the specific data that needs to be collected underpins the decisions and actions in creating a health care plan for on a patient (Dempsey & Wilson, 2009). It is critical to remain free from prejudice in the clinical scene and consistently motivate an individual’s needs and put ethical principles into action. I now feel more aware that my prejudicial judgments can have acute impacts on an individual’s self-concept. Leiniger (1988) stated that nurses must acquire knowledge of the ‘others’ culture in order to provide care that is culturally congruent for the client. Freedom of prejudice enables nurses to seek new information to broaden understanding thus obtaining correct insight to tailor individual action planning that suits the needs of the patient. A nurse’s primary responsibility is conducting a health assessment and collecting patient data (Lewis and Foley, 2010). During data collection, elements of critical thinking establish the determinants for the action to follow. I feel nervous that, my initial assessment on a patient will determine the proceedings of the action plan toward the patients’ treatment and it is expected that nurses demonstrate the knowledge and ability to grow and gain further knowledge through clinical practice and reflection. American Society of Registered Nursing (2007) stated that nurses should develop skills to assess patient’s responses to the illness. Furthermore, every patient differs and has different attitudes on various issues of life and has various levels of understanding and coping capabilities. Knowing the essential elements of critical thinking that underpin nursing assessments and applying them in clinical judgments enables me as a student nurse to  have the confidence to conduct assessments and collect data correctly. Lewis and Foley (2010) pointed out that professional registered nurses or midwives are expected to be able to analyse his or her own practice through reflection. Self-awareness is the foundation of reflective practice thus identifying nurses own needs and seeking supportive networks encourages professional growth and heightened self-awareness. I feel that reflective practice is paramount for any nurse and midwife of any level of experience so that patient’s needs are always met with modern effective treatment and a high quality of care. Today, emotional intelligence is probed as an important characteristic of building successful nursing leadership and enhancing performance (American Society of Nursing 2007) and is now recognised as a requirement for formal authority to practice under the registration, therefore, vitalizing nursing conduct and reducing job related stress. Understanding the importance of reflectiveness, I can implement this practice into my studies and continue practicing into my nursing career. Nurses and other health care professionals must recognise the importance of understanding the fundamentals discussed above and apply them in the health care industry, implementing them precisely to ensure that the focus is on the patient’s holistic health. This ensures that the patient feels informed, empowered by superior communication that places them at the control centre of the decision making of their treatment and ensures that the most positive foundation for an individuals’ care is established, resulting in a positive outcome. Reflecting on that outcome, despite it being positive or negative, constructing continuous improvement and implementing those improvements in future similar scenarios further down ones career line, assists a nurse to ensure effective communication takes place at all times.

Health of Men and Women Essay Example

Health of Men and Women Essay Example Health of Men and Women Paper Health of Men and Women Paper Developments in health and medicine have enabled men and women to live longer lives than their ancestors. Based on a survey conducted by National Center for Health Statistics of the Centers for Disease Control and Prevention, Paddock (13 September 2007) reported that life expectancy of Americans had increased to 78 years in 2005. However, the life expectancy was only 76 years in 1995, whereas in 1955, the life expectancy of Americans was only 70 years. Both men and women are more careful about their health, and dietary requirements since they consume nutritious diet according to their age, undertake fitness programs in heath clubs, and aim for achieving spiritual elevation as well as mental peace through meditation and yogic exercises. In spite of an increase in life expectancy of humans, they are still vulnerable to several killer diseases like heart disease, cancer, stroke, suicide, diabetes, and many other fatal diseases. A few health concerns for men and women along with their preventive measures, top five diseases that claim the maximum lives of men and women, and the effectiveness of fitness programs in professional health clubs are discussed in this paper. Common Health Problems and Their Prevention Both men and women are vulnerable to the impurities of the surrounding environment. Every human has an immune system, which guards against the toxins, the harmful bacteria and viruses, and the allergens. However, there is a tolerance limit beyond which the human body can not cope up with the deleterious disease causing organisms. As a result, men and women become sick when one or more of their organs catch infection. In its report dated April 2, 2009, Centers for Disease Control and Prevention highlighted that heart disease is the number one killer of Americans, with 652,091 deaths annually. Cancer, stroke, chronic lower respiratory diseases, accidents, diabetes, Alzheimer’s disease, influenza, pneumonia, nephritis, and septicemia are the other leading causes of deaths in American men and women. All these diseases that are prevalent in adult men and women, tend to increase in their risk of occurrence with the age of an individual. The risk of occurrence reduces when balanced diet and regular exercises are incorporated in the daily lifestyle. Further, hypertension is often an important factor that causes stroke and heart diseases. Although awareness about these fatal diseases can be effective in preventive their occurrence, it depends on the individual to avert such an occurrence of a life threatening disease by strictly adhering to the prescriptions of a physician, and to avail of the latest medical technology available for diagnosis and treatment. In a shocking revelation from Centers for Disease Control and Prevention, Zamora highlighted that â€Å"women are 33% more likely than men to visit a doctor in general.† Men are considered to be strong and resilient, and that is why, they tend to hide their health problems from others. They ignore bruises and pains, for which women would normally seek the advice of a doctor. Small health concerns, when ignored, and not properly diagnosed in their early stages, lead to life-threatening diseases. For example, let us take the case of lung cancer that is caused by smoking of tobacco, and by exposure to air pollution. Both men and women are vulnerable to fatal lung cancer, but they can reduce the risk of its occurrence by quitting smoking, and by preventing direct exposure to air pollutants like dust, and smoke from vehicles as well as industrial chimneys. National Cancer Institute has reported more than 100 types of cancer including the dreadful colon cancer. Due to a poor intake of dietary fiber by men and women, there is a poor peristaltic movement of the digestive tract, which leads to constipation, flatulence, and an irritable temperament. However, a balanced diet having appropriate amounts of carbohydrates, fats, proteins, vitamins, minerals and dietary fiber can prevent the major health problems in both men and women. The amount of calories intake depends on the age of individual, the gender, and the kind of work performed- active or sedentary. Based on the findings of United States Department of Agriculture, Los Angeles Times (2009) reported that active females from 19-30 years of age, need 2400 calories per day, while active males in the same age group need 3000 calories per day. The requirement of calories per day is 2000 for sedentary females in the age group of 19-30. The same trend applies to sedentary males: 19-30 age group requires 2400 calories per day. Thus, if the amount of calories be taken according to the discussion, the major health problems in men and women can be prevented. Top 5 Diseases That Cause Deaths in Men Zamora stated that heart disease, stroke, suicide, prostate cancer, and lung cancer are the top five diseases that cause deaths in men. Neglect of their healthcare, and avoiding a meeting with a physician were cited as the two main factors, which aggravate an illness in men to an extent that it eventually leads to an early death. From a study conducted by the Centers for Disease Control and Prevention, Zamora reported that 25% men suffer from a heart disease. It was also stated that men have their first heart attack at the age of 65.8 years, but they could live much longer, if they take diagnostic tests, and proper treatment.
