The Symptoms Of Dementia Health And Social Care Essay
The Symptoms Of Dementia Health And Social Care Essay Dementia is a group of symptoms affecting intellectual and social abilities, severely enough to interfere with daily functioning. It is caused by conditions or changes in the brain. Dementia is the loss of mental functions such as thinking, memory, and reasoning that interferes with a persons daily life and activities, Different types of dementia exist, depending on the cause. Alzheimers disease is the most common type. Dementia is a loss of the mind, it could be static which results from global brain injury or it could be progressive which results in long term decline in cognitive function (Hopkins). Dementia indicates problems with at least two brain functions, such as memory loss along with impaired judgment or language. Dementia has never been known to be a disease but a group of symptoms that causes diseases and conditions, some symptoms are changes in personality, mood, and behavior. Dementia can make someone confused and unable to remember the names and important people in the ir lives like the name of children, husband, sisters and brothers. Some cases of dementia can be treated or cured because the cause is treatable, like dementia caused by substance abuse e.g. street drugs, alcohol, controlled substances, dementia caused by severe depression. This is known as pseudo-dementia (false dementia) and is treatable. In most cases, a true dementia cannot be cured, because of some causes that are curable and partially treated; doctors must be thorough in making the decisions so as not to miss potentially treatable conditions. The frequency of treatable causes of dementia is believed to be about 10 % (WebMD 2010). Dementia is classified as cortical or sub cortical depending on the area that is affected. Cortical dementia affects the cerebral cortex or the outer layer of the brain; the cortex is a sheet of neural tissue that is outermost to the cerebrum of the mammalian brain. It plays a key role in memory, attention, thinking, awareness, consciousness and langu age.it could lead to problems with memory, thinking, and language, difficulty comprehending written or spoken material. Subcortical dementia results from dysfunction in the other brain areas below the cortex; it is the portion of the brain immediately below the cerebral cortex, this is a categorized dementia which can also bring about memory loss, degradation in thinking ability as well as changes in movement and emotions (Hopkins 2010). There are some related Dementia; Mild cognitive impairment is a transition stage between the cognitive decline of normal aging and the more serious problems caused by Alzheimers disease. This disorder can affect the language, writing and reading and could probably cause memory loss. Vascular dementia is the form of dementia that the condition is more than one; it is a group of syndromes relating to different vascular mechanisms. It is preventable and the early detection and an accurate diagnosis are important. Mixed dementia is a condition in which Alzheimers disease and vascular dementia occur at the same time, Dementia with Lewy body is a progressive declined disease or syndrome of the brain with several diseases, especially with two common diseases of older adults, Alzheimers and Parkinsons. Parkinson disease is a degenerative disorder of the central nervous system that often impairs the sufferers motor skills, speech, and other functions, Huntington disease, it is a genetically p rogrammed degeneration of nerve cells in certain areas of the brain. This degeneration causes uncontrolled movements, loss of intellectual faculties, and emotional disturbance. Creutzfeldt-jacob disease Creutzfeldt-Jakob disease is a rare, degenerative, neurological disorder that is invariably fatal and incurable. Normal pressure hydrocephalus is a condition in which there is too much cerebrospinal fluid in the ventricles. This occurs when the natural system for draining and absorbing extra cerebrospinal fluid does not work right. Wernicke-korsakoff syndrome is a neurological disorder that could be acute or chronic which is caused by the deficiency in the B vitamin thiamine, Frontotemporal dementia is a degenerative condition of the part of the brain it is a clinical syndrome caused by degeneration of the frontal lobe of the brain and may extend back to the temporal lobe, It is one of three syndromes caused by frontotemporal lobar degeneration. Dementia has lots of symptoms and all varies depending on the cause, the common ones are memory loss, difficulty in performing activities of daily living, inappropriate behavior, aggitation, personality changes, difficulty with coordination and motor function. Dementia can be diagnoses in different ways; the doctor determines the kind of test, it is important for the doctors to rule out the curable dementia, like depression, normal pressure hydrocephalus, or vitamin B12 deficiency which can cause the same symptoms. Early diagnosis and treatment is important for the patient. The different ways of diagnosing is autopsy to confirm or refine the clinical diagnosis of Alzheimer disease, the patient history so as to help the doctor rule out some conditions, physical examination to help the doctor rule out the treatable and curable cause of dementia and identify some other illness in the body which and coincide with dementia, neurological examination to assess the sensory neuron and motor neuron, especially reflexes to determi ne if the nervous system is functioning and to determine a movement disorder or stroke that may affect the patients diagnosis, lab test to rule out some symptoms like kidney failure that could contribute to the cause of dementia, the test includes complete blood count, urinalysis, blood glucose test, cerebrospinal fluid analysis etc. Brain scan to detect abnormalities of the brain the size of 5 mm and larger, it can also be used by doctors to identify stroke, tumor or other problems that causes dementia, there are different kinds of brain scan which are, computed tomography (CT) which combines special x-ray equipment with complicated computers to produce multiple images or pictures of the inside of the brain. These images of the area being studied can then be examined on a computer monitor, printed or transferred to a CD and magnetic resonance imaging (MRI) used in radiology to visualize detailed internal structure and limited function of the body. Psychiatric evaluation used to det ermine there is depression including sad, hopeless or worthless, or another form of psychiatric disorder which may be contributing to the symptoms of dementia, and presymptomatic testing is used when no treatment available stands in contrast to genetic testing done for the diagnosis of the dementia (White). There is no specific treatment for dementia; the treatment is to treat the cause. Patient with dementia needs to be under the supervision of medical care to focus on the quality care, medication and treatments such as therapy, and family members to help in activities of daily living, and to help the patient cope with many challenges. The goal of treatment is to control the symptoms of the disease; some patient might be hospitalized for a short period of time. The available drugs that the Food and Drug Administration (FDA) approved to determine the treatment of behavioral disorder in patient with dementia is antipsychotic medication which includes, Risperdal, Seroquel, Zyprexa and Abilify, they are used to reduce the psychotic symptoms of dementia and allow the patient to function effective and appropriately (FDA 2005). Drugs for treatment of dementia should be avoided unless they are really necessary, before any of these drugs are prescribed doctors make sure the patient is physicall y healthy, comfortable and well taken care of. Some symptoms that also be treated is when patient is pain, have problems with sight and have difficulty hearing, all this can make patient more confused and increase their vulnerability. It is essential for patients to take the drugs exactly as prescribed to make it effective, but if the symptoms are not controlled the doctor may refer the patient to a specialist for further advice. There are some possible side effects of these drugs that may worsen the symptoms which are muscle stiffness, tremor, anemia, depression, heart failure, infection, nutritional disorder, hypoxia and abnormal movements, which must be listed on the drug guide. The doctor usually starts the medication with low dose and gradually increase the dose until the desired outcome is achieved. It is important to inform the doctor about any other drug that the patient is taking to avoid contraindications and once treatment is established it is important to review it regul arly. In most cases these drugs should not be prescribed for more than three months and patient should not assume that if the has been proved to be effective does not mean it is going to be effective on them. There are some more drugs that can be prescribed which are mood stabilizer (citalopram, fluoxetine, and imipramine), stimulant (methylphenidate) and serotonin affecting drugs (trazodone, buspirone), information on how to take this drugs must be provided by the doctor or pharmacist. What is Alzheimer? Alzheimers disease is a brain disorder named after German physician Alois Alzheimer, who first described it in 1906 Alzheimers, it is irreversible, slowly progressive disease of the brain that is characterized by impairment of memory and eventually by disturbances in reasoning, planning, language, perception memory and thinking skills, and even the ability to carry out the simplest tasks. It is cited as number one mental health among people age 60 and the risk goes up as you get older. The risk is also higher if a family member has had the disease. Alzheimer is a progressive disorder that starts in the brain in the area that involves thought, memory and language. It is characterized by the stage of increasing impairment and dependency (alz.org2010). People with Alzheimer disease may have trouble remembering things that happened recently or names of people. The earliest sign of Alzheimer disease is behavior such as suspiciousness and a thought process heavily influenced by anxiety or fear, often to the point of irrationality and delusion, angry, outburst, withdrawal. Over the time the symptoms of Alzheimer gets worse, they tends to forget how to speak, write, read, brush their teeth, comb their hair and even forget family members this might make them aggressive, wander around, and get stressed. The cause of Alzheimer disease is unknown but lots of factors have been explored. There is no single test that can detect Alzheimer but the disease is diagnosed by some symptoms, some findings on neurological examination and some result from diagnostic test. The tests show the possible sign and symptoms. The pathological hallmark associated with Alzheimers disease is amyloid plaque and neurofibrillary tangles, amyloid is found between nerve cells in the brain. Amyloids are insoluble fibrous protein aggregates sharing specific structural traits that the body produces normally, in an healthy brain the amyloid are broken and diminishes but in an Alzheimers disease the amyloi d form hard and insoluble plaques. Neurofibrillary tangles are also found in the brain of Alzheimer disease patients, this is the accumulation of twisted protein filaments within neurons of the cerebral cortex; a characteristic pathological feature found in the brains of Alzheimers disease patients. In Alzheimers disease, there is an overall shrinkage of brain tissue and theories have proved that there is no cure for it. The part of the brain called sulci are widened while the part called gyri shrunk. The ventricle that contains the cerebrospinal fluid is enlarged. The disease Alzheimer is affecting over 5.3 millions of Americans; it cost over $148 billion annually to take care of an Alzheimers patient (Alazraki). In the early stages of Alzheimers disease, the short-term memory begins to fade, when the cells in the brain begins to diminishes, the ability to perform routine tasks declines. As Alzheimers disease spreads through the cerebral cortex judgment declines, emotional outbursts may occur and language is impaired. As the disease progresses, more nerve cells die, leading to changes in behavior, such as wandering and agitation. In the final stages of the disease, people may lose the ability to recognize faces and communicate; they normally cannot control bodily functions and require constant care. Physicians discuss with the patient and family which tests are most appropriate to establish the correct diagnosis but there is no test that diagnose Alzheimer disease, but the disease is diagnosed by the symptoms, firstly patients have to complete a physical examination to rule out some symptoms, the patient the patient mental status and neuropsychological will be assessed to determine which thinking and memory function may be affected. The patient may have a psychiatric assessment to rule out some mental illness and depression. The patient may be asked to do a brain scan (MRI, CT scan, and PET scan) to help detect signs and symptoms of stroke that can bring changes to the structure of brain associated with thinking. Blood test may be ordered to check for infection, kidney and liver function, electrolyte level, thyroid disorder and other factors that can cause memory loss. Other tests that sometimes provide important diagnostic information include electroencephalogram (EEG), urine t ests, and tests on cerebrospinal fluid (CSF) obtained by a lumbar puncture. The possible drugs approved by the Food and Drug Administration (FDA) are tacrine which should be taken on an empty stomach, one hour before, or two hours after meals. If stomach upset occurs, it may be taken with meals; however, food can decrease tacrine blood levels significantly. The possible side effect of this drug is diarrhea, nausea, vomiting, muscle ache and loss of appetite. Donepezil is expected to delay the onset of Alzheimer disease for about one year in people suffering from mild cognitive impairment; it belongs to a class of drugs called cholinesterase inhibitors, it inhibits acetylcholinesterase, an enzyme responsible for the destruction of one neurotransmitter, acetylcholine. The possible side effects associated with this drug include headache, generalized pain, fatigue, nausea, vomiting, loss of appetite, weight loss, dizziness, muscle cramping, joint pain, diarrhea, insomnia, and increased frequency of urination. Namenda was actually prescribed for moderate to severe stage Alzheimer disease but now is being prescribed even in earlier stages of the disease, Namenda is an orally active receptor antagonist that regulates the activity of glumate in the brain. Cholinesterase inhibitors are used to treat cognitive functions and behavioral symptoms in Lewy body disease. Clonazepam is a benzodiazepine derivative with anticonvulsant and muscle relaxant, it is generally considered to be among the long-acting benzodiazepines and Opiate drugs used to relieve pain. Antipsychotic drugs not approved by FDA are sometimes used to treat agitation include, Risperidone Benzodiazepines and drugs such as Olanzapine , Quetiapine , Ziprasadone .The drugs increase the risk of death in elderly patients and the side effects include sedation, confusion and increased muscle tone.

Gun Control Control Laws Decrease Crime Rates Essay -- Constituton Bil
The United States of America has encountered many problems due to the increase in amount of gun owners which has contributed to the rise of crimes and problems that we face today. Our nation has about 65 million people who own a frightening 240 million firearms. This ridiculous amount of firearms in our nation creates a need for gun control. Gun control laws such as the Brady Act can help solve gun problems and make America a safer place to live. The Brady Act and other gun control laws are effective solutions to our gun control needs. Since the law was started in February of 1994, crime rates related to firearms have fallen 25%. The Brady Act does several things for gun control. First, it makes a waiting period for every purchase of a firearm. This waiting period is of great significance for a few reasons. The waiting period which precedes the sale of the firearm gives the potential criminal time to cool off; therefore the chances of premeditated crimes are lessened. Also during the waiting period, a background check is required for the person trying to purchase the firearm. If the background check shows that the purchaser has been in prison or if they have even one misdemeanor, no sale will take place. The Assault Rifle Ban prohibits manufacturing, importing, and people from owning semiautomatic assault weapons. If a person would like to own an assault rifle they will have to attain a certain license and they also will be r equired to have a background check similar to th...

Advertising and Identity through Consumer Culture Essay
Never before in the history of the modern world has advertising become so prevalent, ubiquitous, and an ââ¬Å"undeniable essentialâ⬠to a modern manââ¬â¢s everyday life than that of our century. Advertising images of all sorts, now flood public spaces: from billboards with eroticized images to the blinding electronic billboard, down to the ââ¬Å"comfort adsâ⬠which oddly stares back in the rest rooms of malls. Magazines and televisions are also full of products that entice the readers and the audience to buy and patronize a certain brand. Similarly, cultural events cannot be seen without a popular brand nor is a sporting event complete without a corporate ad. Indeed, advertising has become part of todayââ¬â¢s culture and has become an inescapable ghost that dominates our media, our road, and our home. The road towards the advertising era began its transition during the 1880ââ¬â¢s to1920ââ¬â¢s. It is during this period that ads focused largely on the products themselves. Products took the center stage, using heavy texts to introduce, feature and market the product. ââ¬Å"Realâ⬠representation of people were absent in advertisements, but rather representation of people who stand for the social values such asà family structure and status differentiation were seen during this stage (Jhally, 1990, p. 228). With the written material properly explaining visual the visual imagery, ads during this period were instructional. At the same time they were also educational as well as promotional. These ads taught the consumer audience how to read commercial messages. However, by the postwar period, education was replaced for a puzzle of numerous visual messages. Visual images then took the limelight during the 1950ââ¬â¢s. Texts were highly reduced and were then replaced by icons and images to allure the consumer. These visual imageries eventually took over the product. The image, rather than the product, became the main message that is communicated to the consumer audience. The once educational ads were now replaced with a hodge-podge of photos and visuals (Jhally, 1990, p. 229). As the 21st century ushered in, the idea of ââ¬Å"identityâ⬠was then marketed to the buying audience, convincing the public that the products they buy represent their identity; identity which can now be brought in the nearest mall and will assure not only satisfaction but happiness as well. This paper will discuss the contemporary culture in the advertising industry as it permeates and even molds todayââ¬â¢s idea of beauty, style, as well as identity. Similarly, it will discuss how people are influenced by this media medium by citing several studies and researches related to the mentioned topic. Apart form this, it will also discuss the benefits and the disadvantages brought about by the culture of advertising. Ours is an era whose society is in constant struggle to find their true identity. Never before has a mankind been so engrossed in a quest for an identity, life, and beauty only to be directed to the market place. Ads that promote images with identity are prevalent. A popular celebrity endorsing this line of clothing, for instance, will give the audience the message that buying these kinds of clothes will make you happy, beautiful, or popular. Likewise, purchasing this brand of shoes will make you a part of the ââ¬Å"coolâ⬠or ââ¬Å"inâ⬠group. Through these visual representations, consumers desire to be like the image they see on ads, and the consumption of this certain product will help them imagine, create, and sustain their idea of themselves, their image, and their identity. The idea of beauty is perhaps one of the most capitalized and used advertising ideas. Numerous magazines often represent a beautiful woman as someone who is skinny, blond, tall, and has a porcelain-like skin.à These faces are evidently plastered on every magazine cover. Of course, a brand logo is placed along side the photo of the model as if saying: You can be just like me if you use this brandâ⬠. Aside from this, almost every celebrity has the same body type. A small or fat woman would consequently mean that she is not conforming to societyââ¬â¢s image of beauty, which therefore automatically makes her ugly. With all of these images, it is no wonder why millions of girls from different parts of the world accept the idea that in order to be beautiful, one should look like a cover girl or a celebrity. This also means that buying that certain skin care line or wearing the same brand of clothes would automatically transform them as they conform to the idea of beauty as well as their identity. In a report which studied the consumption patterns of youth, consumers regard consumption not as a mode of cultural activity, but rather as a rationalized process of fulfilling their desires. This means that a number of individuals actually believe that buying a product will fulfill their desire to look a certain way. Since their idea of perfection is duly represented by images of stunning models and celebrities, their pursuit of what is perfect can only be realized by using the same products or items that these models endorse. Although these ideals of perfection somehow give directions to the consumers, the truth is the images presented are first and foremost unattainable. More often than not, the audience is oblivious to the fact that the images they see, both on screen and on print, has already undergone a process of ââ¬Å"editingâ⬠in order to make it even more perfect. The idea of beauty did not used to be boxed up with the idea of being skinny. In fact, during the prehistoric times, women are portrayed not as a wafer thin woman but rather as a full-bodied female with breasts, hips, abdomen, and thighs. The statuette called Venus of Willendorf for instance, has been revered as a goddess of beauty and fertility. Similarly, the statuette Venus of Moravany and Malââ¬â¢ta are both revered because of their physical attributes. These images of beauty however, began to change as advertising emphasized the need to fit in a size two dress. This is particularly used by companies who promote diet and weight -lose products. Likewise, other manufacturers and business also saw the need to create slimming pills, slimming tea, and so much more. This eventually led other manufacturers to create clothes that will emphasize a womanââ¬â¢s thin frame. Apart from a personââ¬â¢s physical attribute, a personââ¬â¢s lifestyle is also used as a handle by the advertising world to create a market-based image. According to the same report, more than half of the young consumers believed that the products they buy represent their identities and lifestyle in some way. For them, identities are expressed in a variety of products such as shoes, clothes, cosmetics etc. Even seemingly trivial things are supposed to express their lifestyles. For instance, 36 percent of young males answered that their choices of telephone/ mobile equipment represent in some way their identities, and 63 percent of young females think that their choices of hair salon is a representation of their identities (Report on Youth Consumption Trend, 1994, p. 114). The one hour documentary entitled ââ¬Å"Merchants of the Coolâ⬠is perhaps one of the most scathing examinations of how popular culture and advertising are entwined together. Exactly as the title suggests ââ¬Å"Merchants of the Coolâ⬠chronicles how the media both reflects and influences pop culture. A large amount of money is paid to ââ¬Å"cool huntersâ⬠in order to find out what is cool and what is hip. This information is then coursed through mediums such as the television. MTV for example, pay its ââ¬Å"coolâ⬠audiences as well as the hosts and performers to attend to their party to make it look even ââ¬Å"coolerâ⬠. Behind all these happening, there lies a big logo of a soft drinks brand. Much like how a ventriloquist controls a puppet, it is also the same with how a company and how advertising is behind how the image of ââ¬Å"coolnessâ⬠is presented (Frontline, 2001). This construction of a sense of identity, according to British sociologist Robert Bocock (1993), can be seen as a process which may make use of items of consumption such as clothing, footwear, popular music or sporting activities, including being a supporter of particular music groups, singers or soccer clubs. Such consumption patterns could be used as a central means of defining who is a member and who is outside a specific group. It is through material items that eventually determine an individualââ¬â¢s social group, which then ultimately gives him or her identity. A brand is a powerful tool that associates commodities with consumers because it symbolizes various elements of the product so that consumers have relative liberty in finding the association between their identities and commodities. The visual images, even the endorser of the brand also plays a crucial role in alluring the consumer to believe that by purchasing this product, you will become like me or that you will be popular or will have an identity like mine (Bocock, 1993, p. 4). However, the more important question is how does an individual associate his or her identity through the purchase of a certain brand or a certain product? The research mentioned above illustrates the characteristic mentality of a young consumer. ââ¬Å"I do not care about what other people choose. I think of design as an important consideration when I choose things,â⬠and my choices of commodities express a part of my personality.â⬠This statement underlines the prevalent belief that the freedom of choice of the consumer leads to the expression of his or her identity. In other words, since it is the choice of the individual that made him or her wear this particular pair of shoes, this particular pair then represents the identity of the individual who made the decision. Representative form of their self-identities derives from the individual level; individual consumers make a decision by themselves to buy things in order to express their own identities (Hattori, 1997, p.10).

Brass Alloys and Their Chemical Compositions
Brass Alloys and Their Chemical Compositions Brass is any alloy consisting primarily of copper, usually with zinc. In some cases, copper with tin is considered ââ¬â¹a type of brass, although this metal historically has been called bronze. This is a list of common brass alloys, their chemical compositions, and the uses of the different types of brass. Brass Alloys Alloy Composition and Use Admiralty brass 30% zinc and 1% tin, used to inhibit dezincification Aichs alloy 60.66% copper, 36.58% zinc, 1.02% tin, and 1.74% iron. Corrosion resistance, hardness, and toughness make it useful for marine applications. Alpha brass Less than 35% zinc, malleable, can be worked cold, used in pressing, forging, or similar applications. Alpha brasses have only one phase, with face-centered cubic crystal structure. Princes metal or Prince Ruperts metal Alpha brass containing 75% copper and 25% zinc. Its named for Prince Rupert of the Rhine and used to imitate gold. Alpha-beta brass, Muntz metal, or duplex brass 35-45% zinc, suited for hot working. It contains both and phase; the -phase is body-centered cubic and is harder and stronger than . Alpha-beta brasses are usually worked hot. Aluminum brass Contains aluminum, which improves its corrosion resistance. Its used for seawater service and in Euro coins (Nordic gold). Arsenical brass Contains arsenic and frequently aluminum and is used for boiler fireboxes Beta brass 45-50% zinc content.

Physical Education Thesis 10 Facts That Will Make the Research Hooking
Physical Education Thesis 10 Facts That Will Make the Research Hooking When students search for good physical education thesis topics, they face the problem of proper facts selection. They must be verified, and every sentence must be informative. Besides, a student must follow all recommendations. One of them is a good paper structure. A thesis structure should be the following: Title page Abstract Contents Chapters (background, literature review, methodology, data analysis, discussion) Bibliography Appendices One more important feature of a thesis paper is that it must be 100% plagiarism-free. Itââ¬â¢s important to avoid using many citations. Itââ¬â¢s necessary to analyze facts and reflect them in your paper. Itââ¬â¢s also important to remember sources mentioning in the bibliography. 10 Physical Education Facts to Make the Research Hooking The thesis is an academic paper that requires not only proper knowledge of the subject. It also requires the ability to organize received facts according to the needed format style and, naturally, it must be logical. More than 35% of American children from two to nineteen suffer obesity. When such kids grow up, they become many chronic health complications which lead to a lethal end. In the United States, 75% of adults also have extra weight, 41% of which suffer obesity. Physical Activity Guidelines proves that children must have no less than one hour of physical activity daily. Thatââ¬â¢s why school program provides children with not less than 30-minutes activity. The curriculum follows the national recommendation that is 2 hours 30 minutes in elementary school weekly and 3 hours 45 minutes in middle and high schools. Proper physical activity can prevent many diseases including heart diseases, high blood pressure, metabolism disorders, osteoporosis, cancer, and even depression. Lack of exercising can provoke energy imbalance and weight gaining. The statistic shows that approximately 23% of adolescents and adults and 81% of teenagers and schoolchildren lead inactive or sedentary way of life. Adults spend their time working in offices, and children watch much TV or play computer/smartphone games. A great number of people confuse physical activity and sport. In fact, physical activity includes all movements produced by the human skeletal muscles including walking, gardening, cleaning, playing, etc. Sport is a professional or amateur performance like races, box, tennis, football, etc. A sports activity requires strict rules and physical activity doesnââ¬â¢t need them. People above 65 must be active and need to be active nearly 150 minutes per week. Those who canââ¬â¢t be active because of poor health condition must move as much as possible. If a person canââ¬â¢t run, he/she must, at least, walk and not spend much time lying or sitting. In case a person canââ¬â¢t walk, itââ¬â¢s necessary to find the activity that can fit the person. Individuals who move with the help of the invalid chair can do specific exercises to improve the functioning of the upper part of the body. The researchers have found out that only 21,6% of American teens aged six to nineteen lead active ways of life. It means that they spend more than 60 minutes on sport or vigorous physical activity. The statistic includes data based on childrenââ¬â¢s daily schedule on working days (Monday Friday) and doesnââ¬â¢t contain information about their weekends. Muscle strengthening exercises became very popular among high-school students in 2015. Nearly 54% of all adolescents went in for weightlifting, push-up, street workout, and other types of exercising three days a week. Experts suggest 30-minutes aerobic activity per day for expectant mothers and during lactation. Such physical activity helps control weight and isnââ¬â¢t risky. One more strong scientific evidence is that pregnant women can avoid various complications like high blood pressure (preeclampsia) and gestational ( inside the womb) diabetes. Physical activity doesnââ¬â¢t affect the amount of breast milk and its quality. People with physical disabilities should have 150 or 75 minutes of moderate-intensity activity every week. Thatââ¬â¢s 10-25 minutes of physical activity daily. Experts recommend going in for aerobics and muscle-strengthening activities. Those who cannot cope with such load should just avoid passive ways of living and engage in activity regarding their physical abilities. Experts differentiate between 4 types of physical activity: Passive or inactive; Low activity (less than required); Medium activity (more than required ââ¬â up to 4,5 hours a week); High activity (more than 5 hours a week). Proper exercising reduces the risk of death at the age considered to be less than average one for a specific population group. The scientific researchers together with health providers proved that people who are active 560 minutes a week (7 hours) have 40% fewer cases of cardiovascular diseases and cancer than those who are active half an hour weekly.

The Drinking Age Essay Example | Topics and Well Written Essays - 500 words
The Drinking Age - Essay Example This phenomenon is known as ââ¬Å"bingingâ⬠when the young adults begin consuming above the average amount of alcohol a body should consume- often they do this action as a sign of rebellion against the institution and the authority. A study conducted by Indiana University showed that 32% of underage drinkers are heavy drinkers as compared to the 24% of legal aged drinkers (Engs). The most underage drinking is observed by college students who while trying to get initiated into fraternities try to impress their peers or simply just because they get the chance to experience drinking. Many of the problems affiliated by drinking such as getting low grades in class, skipping out classes due to overdrinking the previous night, and getting into fights due to drinking are observed to be higher among people falling below the age of 21. The incidents of such acts occurring over the legal age are relatively less. It is recommended that young adults should be given proper awareness of the effects of alcohol and they should be permitted to drink alcohol in a controlled environment where they can be observed and assisted if they face any complications. That may be a reason why more than 100 college presidents signed a petition to lower the drinking age (Roan). One of the arguments in support of the 21 age restriction is that there has been a noted decrease in the number of traffic accidents caused by young adults who were intoxicated. But the decrease could also be attributed to more awareness of the effects of drinking while driving, implementation of designated driver programs, lower speed limits and free taxi services from drinking establishments. So the argument placed that it is solely the implementation of a higher age limit which has reduced the number of car accidents is incorrect. The drinking age should be decreased to 18.
