> How do you listen to audio books when you're engaged in other activities?

The same way you can probably carry a conversation while walking. As long as the other activity doesn't engage the language processing part of the brain there's no conflict. I can't listen while reading, not even small package labels in a grocery store, but I can easily listen while washing dishes or exercising or eating a meal because different sections of the brain are responsible for them and can be active simultaneously.
