Audio books are great alternatives to traditional reading. This piece of technology allows you to complete another task while listening to an audio book to stimulate your brain.
The narrator plays the most important aspect on how your brain interprets the book. There is no definite way to figure out if a narrator is good unless you listen to him or her yourself, or read reviews from a variety of websites. A website such as Audiofilemagazine is a good places to start.
Audio books work the same as a Movie or CD, you simply pick up where you left off. Tracking your progress as you listen to an audio book should not be difficult if you manage the recordings on your own. You may want to replay the previous 5 minutes of the audio book to refresh your memory on recent events so you can get a good grasp of the story when you continue to listen to your book on a given day.
If you want to maximize your listening experience limit the amount of activities you complete while you listen to your audio book. For instance, it should be much easier to listen to an audio book while on a plane as opposed to when you are driving. Listening to an audio book while lightly cleaning your home is another way to make sure you are able to digest the information you are hearing.
