Chrysalis

Think about it - if caterpillars approached the changes that come with getting older in the same way many humans do, we'd have no butterflies.  They'd refuse to spin the cocoon, let alone allow almost 100% of their ground-walking selves dissolve into something different.  But, unlike humans, they don't "know" any better.

 
Who are the clueless ones?  The caterpillar, who accepts as nature's way the changes necessary to become something unimaginable, or the human, kicking resisting denying that any change is happening, let alone accepting that it is nature's way, the gateway to something equally unimaginable & just as spectacular as a butterfly.
