To put it simply,
We
Are made of nothing
But brittle skin
& fragile bones
That will end up
Completely worthless
Left alone for eternity
to rot.
Our red blood
Sails throughout our veins
Like a sailor
On the calm ocean;
But once the wind begins to stir
The oceans become
Rough  
And you're left there
to eventually drown.
Our hearts,
All serve the same purpose;
To beat to the rhythm
Of the song
that keeps your body from shutting down, that keeps you breathing.
It has the most complex job,
Such a fragile thing
That is expected to
Take care of so much.
The heart is where
Your deepest secrets lie.
Where your fears are hidden.
Where pain left its marks.
Your dreams are burried deep within.
Your favorite memories,
Along with the bad ones too,
Are swimming around inside.
Our hearts,
Are made up
Of things we cannot humanly explain;
It is beyond being capable
Of truly being expressed with
Mere words on a page
That will be crumbled up
Thrown out,
Never serving
any true purpose.
There are Things
In the heart
That will overpower it all;
Every detail in your life
Is now determined
On the unknown effect
it will leave.
Things,
That will make you see
Mountains with endless heights,
When there's really only
Hills in front of you
That you can walk on top of
And crush.
Our hearts,
They are consisted
And constructed
For the action
Of
Loving and being loved,
Even if vulnerable.

My heart,
To sum it all up,

Is made up
Of all the things
You do
That keep me breathing
That keep me from dying

You, are my heart.
