Uncle Yoda

I have observed that old men become more compact as they age and that they begin to look like small benign wizards - our collective Grand Uncle Yoda adept in mystery, bestowing lessons to those who care to notice...

Yeats says it better...

"That is no country for old men;
An aged man is but a paltry thing,
a tattered coat upon a stick,
unless
Soul clap its hands and sing."
