I wonder how people will look back on coffee hundreds of years from now. "Almost everyone used to constantly drink an addictive stimulant. Shops on every block sold it. People stated that they couldn't function (or even talk) in the morning until they had consumed the stimulant. At work, people needed to take constant stimulant breaks. If someone went a day without it, they often suffered debilitating headaches." It sounds like dystopian science fiction.

(To be clear, I'm not opposed to coffee. It's just one of those things that seems strange if you think about it from a distant perspective.)
