Immortality

My coldhearted
scientific mind
reminds me
that in just a few decades
your body is going to
shut down for
the purpose it was made.

It will stop injecting
eggs into your womb
even though you were
born with them and had
them in you before you
were ever fertile.

Your monthly flow will
cease in fits and starts
until it ends all together
and the eggs that still
sit inside you
will go unused.

I know that fact
so what tells me
that long after your
fertility ends I am still
going to want your
body?

How do I already know
I will still crave
touching you
long after it serves
any reasonable purpose?

My rational mind
tells me that when we die
we will be food for the Earth
as bacteria and tiny animals
and plants will make compost
out of us.

Our bodies will have no
more adenosine triphosphate
and we will cease to move
or to remember or to
perceive anything around us
just like the lumps of carbon
and water we are.

So in spite of every
radiological scan I have ever had
failing to find something that
can be called a soul
why do I feel like
I will never leave you
even after I have dust for blood?
