Describe a topic, idea, or concept you find so engaging that it makes you lose all track of time. why does it captivate you? what or who do you turn to when you want to learn more?

I sense that this is a subjective question. Well, for me, I find great interest in the HBO TV series, Game of Thrones. It is because of the unpredictable plot, the well-thought story and the high investment on the production. I tend to discuss the events that happened in the series with friends who also watch it. Other times, I read online fan theories just to suffice my curiosity.
