Benefit from 50 books every year

The first time a friend of mine said - "I benefit from reading 50 books each year... in my spare time", I didn't believe it .
Knowing how demanding her time was because of her top position in her job and because she is a single mom, I was certain she was exaggerating ..She insisted that it was the truth ! I would have continued arguing with her until she pointed out to me that she didn't have to actually "read" them , but they were "read" to her while she listened... in her spare time.
She then went ahead and played an audio book on her CD player for me to listen to .She told me that this was how she had almost any book she wanted "read" to her as audio books while she prepared for work in the morning , while she prepared her daughter for school , while she did her exercises each day , while she commuted to and from work and any free time she had on hands that didn't involve using her mind .
