(NEW YORK) -- Thursday marks National Coffee Day! To celebrate you can pick-up a free cup of Joe at Krispy Kreme and 7-Eleven.
Coffee was allegedly first discovered by a goat herder in the 9th century who noticed his goats acting strangely after eating the berries off the coffee plant.
Something you might not know about your beloved caffeine source: contrary to popular belief, light roast coffee actually has more caffeine than dark roast.
Also worth noting: more than 500 billion cups of coffee are consumed each year; more than half at breakfast. And it’s the second most traded commodity -- behind oil.
