From Amsterdam to Zimbabwe, this ubiquitous drink has delivered the power of caffeine to the world since it was legalized. The business community has been fueled by coffee breaks, going back to the 1950s. Most would agree that the benefits of drinking coffee outweigh any negative side effects. On the positive side: more energy, decreased hunger, less tired, flushing of the skin (see picture). Possible negatives: anxiety, confusion, irritability, insomnia. One cup of coffee provides about 100 mg of caffeine, which allow me to create early morning blog posts such as this one.
