Coffee makes you do work

Coffee makes you do work

When we drink a caffeinated beverage, the caffeine quickly crosses the blood-brain barrier—an interface of sorts between the brain and the body’s circulatory system, designed to protect the central nervous system from chemicals in the blood that might harm it—and proceeds to block the activity of a substance called adenosine. Normally, a central function of adenosine is to inhibit the release of various chemicals into the brain, lowering energy levels and promoting sleep, among other regulatory bodily functions. When it’s blocked, we’re less likely to fall asleep on our desks or feel our focus drifting.

The reason why you need coffee to excute an idea but beer for creativity.
