Kids and adults of today have cable with hundreds of channels, access to movies at home, cell phones, iPods, computers, tablets, etc.
Where I used to be able to read a book while watching TV or listening to the radio, now we have a hundred other distractions to keep you occupied. Look at the effect social networking has on your ability to focus, or at least my ability to focus.
I'm just saying that perhaps all of the extras that are now a part of our lives may contribute to how we are unable to focus on certain things as easily as before. Food for thought, anyway.
