Microfractures

When it was too late to stay awake

But too hot to fall asleep

Last night

I learned about microfractures

Where, if I understood correctly,

Bones are broken again and again

And when they heal, they get stronger and stronger

And this is done by fighters

To strengthen their bones

Until they can even

Break through stone

And I wondered if human hearts

Worked like this too

Where with each blow

They get stronger and stronger

And I thought of you

Pictured you reaching behind your ribs

Grabbing your pulsating heart

And finding cold, hard stone

With edges so sharp they cut the bruised skin of your hand
