Alright - I read a research paper once that said that as humans, are taste buds are naturally repelled by bitter flavors, that includes coffee as well. Drinking coffee is an adaptation, you could say, brought on by society and social customs. Which is fine, but when you think of it, most people can't stand the flavor of coffee at first, but slowly learn to like it.
Tea, on the other hand, can be bitter, but our tongues are more adapt to it than to coffee. Besides, tea just tastes so much better. And it makes you feel sophisticated. #TEAFORALL
