It is a well established fact that people are not trees. Seriously, ask anybody.
But what if we were like trees in just one way, what if we showed our growth on the outside? What if with each passing year we grew taller and thicker? What if the oldest and wisest among us were the biggest and most majestic?
Not that would necessarily be a good thing, it might get a little out of control if we had an army of centenarians crashing around knocking into things with their bough-like arms. Imagine how much different the world could be if we as a society could recognize wisdom on the spot. We would seek out the tallest and thickest elders to ask them for their wisdom.
Would that be a world you would want to see?
