Lol. You know why you laughed right?
Coffee is not a food, it is under the category of beverages and can be paired with a variety of dishes or snacks which together is seen as a meal or food. You get, right?
I know you like taking coffee alone, so it's not food. Haha.
No I dont get it.
You can live on coffee. So I think you are mistaken. Coffee. Cigarettes. Sex. And some good rock songs.
One can live months on it.
