a boost to mental functioning will ultimately hurt us because it encourages us to try to fix our mind with substances any time we feel out of sorts
Coffee is said to be good for students because it stimulates their mind and assists in their studying, unless they experience severe side effects. Some people claim black tea is a better option as it has less side effects, but black tea still has side effects and doesn't provide the same stimulation as coffee. Others feel that any mental stimulation only encourages addiction; however, this argument has no basis because with the same logic, thirst for water would result in addiction. Enjoy coffee in moderation to boost your productivity and make your work more enjoyable.
