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.

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
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 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.

Throughout the nation catastrophes occur on a daily basis; however there are a few catastrophes that have taken national precedence and left a traumatized nation. Most usually these catastrophes are an act of terrorism. Michael Nelson (2010) describes the nature of such terrorism catastrophes as disconcerting, unanticipated and that unnerve “the country’s sense of safety and identity” (p. 20). When such “a traumatic event results in the death of civilians” and “calls the nation’s institutions or values into question” the nation as a whole looks to their leader, our president, to offer solace and calm through a responsive speech (Campbell and Jamieson, 2008, p. 102). In Presidents Creating the Presidency, (2008) the authors have labeled these speeches as a national eulogy in which they usually occur at the sight of the
Scrutiny of caffeine and its effects has increased dramatically in the last 20 years, due in part to an increase in consumption of caffeine. In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings. However, the results from these studies are inconclusive and often somewhat contradictory – many studies (such as that by Tetsuya Ohara et al.) show that caffeine is a great boon to
Caffeine, also known as methyltheobromine, is a central nervous system stimulant that humans consume on a daily basis. Found in coffee, tea, and other caffeinated beverages, caffeine has many side effects.

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 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.
Specific speech purpose: To persuade the class that emotional/mental health is important, and is in fact even more important than their physical health.
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.
Preview: The potential effects are related to the main ingredient in coffee – caffeine. Caffeine is a drug that stimulates the central nervous system that increases alertness and energy, but it is also very addictive.
When a person drinks coffee, the caffeine is absorbed into the bloodstream and then travels to the brain where it blocks an inhibitory neurotransmitter called Adenosine. When this happens, the amount of other neurotransmitters actually increases.
