Mood Enhancer
One study of more than 86 000 female nurses by research of Harvard Medical School looked for a correlation between caffeine consumption and suicide (Klosterman, 2007). Nurses who drank tow or more cups a day were less likely to become depressed enough to commit suicide (Klosterman, 2007). A similar study were conducted with nearly 130 000

Biochemistry investigates the mechanism of caffeine and how it affects and benefits the human body.

Future of Caffeine According to Bennett Alan Weinberg and Bonnie Bealer (2001)
Chemical intoxicants have been widely enjoyed since the remotest prehistoric times. Today, caffeine is the dominant universal drug of human race. Certainly caffeine use has not remained constant, nor can it be absolutely asserted that its use has demonstrated an unbroken increase in every nation in every decade. Yet coffee bean alone has come to an account for a greater share of international trade than any other agricultural commodity and caffeinated beverages have reached every quarter of every country on earth. Selling caffeinated beverages is and is likely to remain a great
