Drinking coffee has become a crucial part of the daily routine of 110 million Americans. Over the past 20 years, over 19,000 studies have been conducted to examine the impact of coffee on one’s health. There appears to be both benefits and potential hazards associated with this drink. Some studies have shown that coffee may reduce the risk of diabetes. After analyzing data on 120,000 people over an 18-year period, researchers at Harvard have concluded that drinking 1 to 3 cups of coffee each day can reduce diabetes risk by several percentage points, compared with not drinking coffee at all. Caffeinated and decaffeinated coffees provide similar results, which suggests that a coffee component other than caffeine may have beneficial effects on blood sugar levels. Researchers also find that coffee can lower the risks of Parkinson’s disease, colon cancer, and gallstones. On the other hand, some researchers have found that coffee is not for everyone. In excessive amounts－meaning more than whatever one’s body can tolerate－coffee can decrease the flow of blood to the heart, increase blood pressure, and cause rapid heartbeat. In addition, pregnant women should limit their caffeine intake because fetuses are sensitive to caffeine.

        Hipsters are a subculture of men and women typically in their 20s and 30s living in urban areas. They are typically described as affluent or middle-class young Bohemians who, with a varied non-mainstream fashion sensibility, value independent thinking, counter-culture, progressive politics, an appreciation of art and alternative music, creativity, intelligence, and witty banter. The term in its current usage first appeared in the 1990s and became worldwide popular in the 2010s. 

        Hipsters tend to be well educated and often have liberal arts degrees, or degrees in mathematics and sciences, which also require certain creative and analytical thinking abilities. Consequently, many hipsters tend to have jobs in the music, art, and fashion industries. Hipsters are also very racially open-minded, and the greatest number of inter-racial couples in any urban environment are typically found within the hipster subculture. 

        Although "hipsterism" is really a state of mind, it is also often intertwined with distinct fashion sensibilities. Hipsters reject the culturally-ignorant attitudes of mainstream consumers. In comparison to the much larger mainstream mass, they are pioneers and leaders of the latest cultural trends and ideals. For example, the surge of jeans made to look old and worn, that have become prevalent at stores such as The Gap, American Eagle, Abercrombie and Fitch, and Hollister, were originally paraded by hipsters who shopped in thrift stores years before such clothing items were mass produced and sold to the mainstream consumers. 

        The true irony here is that many people who look down upon hipster culture are in fact unknowingly following a path that hipsters have carved out years before them. This phenomenon applies to music as well, as many bands have become successful and known to mainstream audiences only because hipsters first found and listened to them as early-adopters of new culture. Once certain concepts of fashion and music have reached mainstream audiences, hipsters just move on to something new and improved. 

        Nowadays, the word "hipster" is used in a mixed sense—both positive and negative. In a less positive way, it is often used to describe someone who is pretentious, overly trendy, or overrefined. Interestingly, members of the subculture typically do not self-identify as hipsters in either sense. Some analysts contend that the notion of the contemporary hipster is actually a myth created by marketing to serve various kinds of commercially-related purposes.
