Tonight driving home from dinner out, we passed a young man walking along the road. We all looked at him and then looked a second time. His ears were plugged into an MP3 player or discman and as he walked he was not looking at the road at all. He was reading a book.
I guess he could multi-task!
I am pretty sure that I would not be able to concentrate on a book well enough to enjoy it and walk at the same time, and then to listen to music at the same time!
