But learn we should. It is a waste of this precious god-given gift to allow our brain cells to atrophy or our hearts to harden with old jaded blood. There is still more that we can do to and with our lives. All that we need to do is .... learn and learn some more! When you do that you will be in for plenty of surprises unimagined nor ever dreamed of before.
Now this 'teaching'.... As we are eternal students of life, so too are we as 'teachers'. Not as our teachers of those good old days of school but as teachers of life and living. We teach by the way we live our lives. It is true that we all stand connected. Whatever you do with your life will impact, affect, or influence another person in his own, for good or for bad....directly or indirectly. As says this beautiful quote...........
“No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a cloud be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.” ― John Donne, No Man Is An Island
In short, we each are both teacher-and-student to one another.
