Caffeine is the most popular stimulant in the world. We researched this topic and found out that many studies have been done to prove both the upside and the downside to caffeine. The upside is that, in moderation, caffeine increases alertness and focus, improves memory, and boosts mood and energy. The downside is that caffeine over stimulates the nervous system, leading to irritability, insomnia, headaches, nervousness, high and irregular pulse, elevated blood pressure, heartburn, dehydration, and may increase birth defects during pregnancy.
There is a legend that says coffee was discovered around 850 AD in upper Egypt by a goat herder named Khaldi. One night, Khaldi's goats did not return home. When he found his goats, Khaldi saw them dancing around a shrub with red berries (coffee beans). After Khaldi tried some of the berries, he started to dance too. Khaldi spoke with some monks who used the berries to make a drink and... "coffee was born."
