I am always amazed at how many people feel any down time, no matter how little, is a waste of time. Our minds need rest also at times. I enjoy my down time, it helps clear the head, sometimes it's a chance to give my computer strained eyes a rest. Reading a book is the best way for me to rest my mind for a bit, as I tend to get lost in books. Now that I have a car again, I miss my reading time while on the bus! I'll have to look into the audio books for when I'm driving.
