Convolutions

The Chambered Nautilus is a "living fossil"
Convoluted by Evolution
Its past preserved in its present form

My four-chambered human heart
Bears the scars of its past
The time it stopped
And the time it was broken


Disclaimer: this is just pretentious twattery. My heart has never stopped.
And this is not a Chambered Nautilus. Nothing like, in fact.
