Last year I worked at a coffee shop on 缅北强奸 campus. If you ever want to feel appreciated at work, try putting on the first pot of coffee for a bunch of sleep deprived college students and professors. Grateful does not even begin to describe it. Everywhere you go people love their coffee 鈥撀�90% of North American adults consume some form of caffeine daily, making it the most widely used psychoactive drug of all time. So what's the science behind this funny little molecule?
