Turning Off Your Brain

Have you ever stopped at the end of a day and tried to rememeber all of the things you had done that day? Have you ever stopped and tried to simply remember if you had thought of anything important during your day?
Every now and then someone will ask “what are you thinking?” and more often than not my response will be nothing. Is it possible to not truly be thinking of anything?
How many times have you sat in a class or church then as soon as you walk out the doors forget everything you just heard? Do we truely listen or do we train ourselves to turn our brains off?
There have been days in which I have gone to school or sat in front of a tv and never really thought of anything of importance during my day. How many times have you been sitting somewhere with nothing to do and became bored. 50 years ago people used their imaginations. They used their brains and were not as bored as we are today. Is this a result of modern technology and instant communication? Are we at the point in our world that there are no more great thinkers? How often do you sit down and contemplate anything of significance?
The only times I ever feel I truely stimulate my brain are when I occasionally read a book. This is something that needs to change. We need to expand and use our minds to the fullest. Yet it seems I use mine less and less as I grow older. What do we have to do to change?
