Reading Audio Books while playing Lol

I was in a norm the other day, and was listening to music at the same time. So in between two of the songs I heard an advertisement about politics or something. I didn't realize that I was listening to an ad until it was about 1 minute through. So I went to press the "Skip Ad" button once I realized that this was an ad. But the cool thing was that I actually found that I was listening to the conversation in the ad and I could comprehend and recall what was going on. So then I remembered that I had to finish reading a book for school soon, so I turned on the audio book for it and listened to it while playing and it actually worked! I guess since most of an average LoL game is just mindless farming, you can do something productive in the meantime!
