The use of Audio Books in Equator Man

I didn’t know that the main use of the audio books was for blind people, until I saw the Korean TV series entitled, The Equator Man. I started using audio books when I got lazy reading. Back then I thought it was for lazy people like me. So, it is clear now. It is good to know that audio books have its good purpose. Now whenever I see audio books online it gives a smile on my face.
