Why is Korean food so spicy?

If you've ever had Korean food, one thing you know is that they like their spice. But why do Koreans love spicy food? This episode looks at the history of gochu, a distinctly Korean spice, including theories about where it came from and why Koreans love it so much. My usual humorous approach to the topic, including several fun anecdotes from my own personal experiences with Koreans and spicy food. Spicy!
