In the Wild, few species reach old age. One way and another, Rhinos run out of steam or die in the process of Living. We don’t see this as tragic; for most of Us it is inevitable.
For the oldest of Us, what comes of so much Expereince is a sense of calm. We fret less about our Ignorance and embrace it, or accept it as Natural. We can’t know it all. We can’t even Want to know it all.
We accept our days for what they offer, and let it go at that. Maybe that is what Wisdom offers.
