All people have to sleep some time and all people have to stay awake as well. This is what the caffeine in coffee brews offer, especially the black brewed coffee known to give that extra kick to wake up the drowsy eyed person.
Offices store coffee for a reason. It is not primarily because your boss would want a cup every time he walks into his office. It is a necessity for people who need to work hard on routine work and at times during extended hours to get the job done. Deadlines are the easiest underlying culprits to which people need to resort to drinking coffee to keep them awake.
It has been proven over the years that coffee wakes up minds. But the consumption level should also be monitored since excess intake may lead to nervous misalignments and may be bad for the overall health of a person especially if he abuses his health and lacks the necessary sleep to recharge his normal stored energy.
