In the story “Java Man” by Malcolm Gladwell, he talks about how caffeine became what it is today. He starts off his essay by talking about caffeinated drinks. Then Gladwell goes into details talking about tea, soda, and coffee. Gladwell’ s main point in the essay was how caffeine affected our society. Gladwell breaks down the evolution of caffeine over the years. He also talks about coffee houses from the 18th century and how they gave birth to a new era of caffeine drinkers. In my opinion, Gladwell’s arguments and researches are very interesting. For someone to research the effects on the human body of caffeine and research what’s in coffee, tea and soda, and on how each vary from each other is very engaging, also he does a very good in supporting his arguments. Even though I do not drink coffee myself, I agree with him that caffeine can be considered a drug and that it greatly impacts our society today, but I also believe that caffeine can be considered a good thing and people shouldn’t …show more content…

“Java Man” by Malcolm Gladwell is an essay describing caffeine, its uses, and social standing. The essay describes how this particular stimulant has been widely accepted by society throughout time. Malcolm Gladwell recounts how caffeine appeals to different classes when used in different beverages; gives examples of how this legal stimulant affects the body for different individuals and gives examples of a very short and unconventional study, which showed the harmless affects of caffeine; and is consumed by a variety of age groups in many ways. Malcolm Gladwell says it best in his essay, “Java Man”: “At one moment, in one form, it is the drug of choice of café intellectuals and artists; in another, of Zen monks; and yet another, of children enthralled by a fat man that slides down chimneys” (233). The setting and
Malcolm Gladwell, in order to make his argument seem credible, utilizes specific writing techniques. Gladwell frequently uses anecdotes about successful individuals as examples to further strengthen his argument. Gladwell write that, “One warm, spring day in May of 2007, the Medicine Hat Tigers and the Vancouver Giants met for the Memorial Cup hockey championships in Vancouver, British Columbia” (Gladwell 15). Frequently, Gladwell starts each chapter with a story about an individual group. These stories showcase the events and lives of successful people and are followed by Gladwell’s analysis of their success. By using specific, descriptive anecdotes, Gladwell is proving the credibility of his argument. Instead of just reciting his analysis,
Probabilistic reasoning is difficult. People prefer to reject ambiguity and demand that concrete predictions be made. However, intelligence is inherently ambiguous. In intelligence forecasting, it is difficult to determine what information constitutes a signal, and what constitutes noise. In “Connecting the Dots: The Paradoxes of Intelligence Reform”, Malcolm Gladwell analyzes several high-profile “intelligence failures”, such as the Yom Kippur War, September 11th, Pearl Harbor, and the Bay of Pigs fiasco, as well as several psychological studies, and comes to the conclusion that: (1) there is no such thing as a perfect intelligence system - all systems require tradeoffs; (2) failures do not constitute the limitations of the intelligence community,

Also, writing about controversial issues to establish credibility with the readers. These techniques are found in “Offensive Play”, “Small Change”, and “Harlan, Kentucky”, works by Gladwell.
This informative speech is talking about the effect of caffeine on human body. At the beginning, the speech explains that caffeine can be absorbed by human body in only 30 to 35 minutes after consuming. Then, the speech explains that caffeine can be found not only in coffee but also in energy drink, chocolate, candy bar, and some certain medicine. On the next part, the speech describe that caffeine can affect the three major systems in human body. The first one is the nervous systems. Consuming caffeine can increase the rate to send impulses in the nervous system. In the other word, the process of sending messages can be done quicker. This is one of the good effects of caffeine in our body. The second one is the cardiovascular systems. Caffeine gives a bad effect in our cardiovascular systems by raising the blood pressure and takes a part in building up fatty acid in the heart. That fatty acid can cause blood clot that occurs when blood hardens from liquid to solid. The third one is the urinary systems. Caffeine can disrupt or increase our urinary frequency. In this case, caffeine on...
Caffeine is a bitter white alkaloid found in coffee, tea, and kola nuts and is used as a stimulant and diuretic. It is a stimulant, which means it increases your heart rate and metabolism and makes you feel more alert. If pregnant you should do best to limit yourself to 200mg of caffeine a day. If you regularly have more than 200mg of caffeine during your pregnancy, it could increase the risk of a miscarriage or your baby having a low birth weight. A low birth weight may mean your baby has some health problems when he’s born or in the future.
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

Caffeine also increases dopamine levels in the same way that amphetamines do (heroine, and cocaine also manipulate dopamine levels by slowing down the rate of dopamine reuptake). Dopamine is a neurotransmitter that, in certain parts of the brain, activates the pleasure center. Caffeine’s effects are obviously much lower than heroin’s, but it is the same mechanism. The long term problem with caffeine is the effect it has on sleep. The half life of caffeine in your body is about 6 hours. That means that if you have a big cup of coffee with 200 mg of caffeine in it at 3:00pm, by 9:00pm about 100 mg of that caffeine is still in your system. You will still be able to fall asleep but your body is going to miss out on the benefits of deep sleep. The next day you are probably going to feel worse, so to make yourself feel better, you will need caffeine as soon as you get up and out of bed. This cycle can start to continue day after day. This is why 90% of Americans consume caffeine everyday. Once you get in the cycle, you have to keep taking the drug (home.howstuffworks.com).
Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall health.
By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.
Beverages containing caffeine, sugar and niacin (vitamin B12) can lead to serious health problems. According to caffeine informer, one of them is cardiac arrest. While caffeine calculator can show limitation of energy drinks, everyone does not follow this rule. Those with heart problems are at the high risk to face cardiac arrest after only small amount energy drinks. Next are headaches and migraines, excessive energy drinks can lead to extreme headaches from the caffeine withdrawal syndrome. Changing the amount of caffeine people ingest daily causes more frequent headaches. A very high amount of sugar is responsible for damage the insulin producing cells of the pancreas which leads to type II diabetes. Excessive consumption of energy drinks can also lead to vomiting and thus, causing dehydration and acid abrasion of teeth and oesophagus. They can also lead to hypertension. For those with normal blood pressure, this is not affecting, but those with previously increased blood pressure could be leading themselves at risk of cerebral vascular stroke and other problems related to high blood pressure, after consuming high amount of energy drinks. The American Heart Association (2017) showed that energy drinks causes a significant negative effect on blood pressure than drinks that contain caffeine alone as the active ingredient. In addition, niacin is placed in most energy
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health detriments and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect. The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industries.
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
