"Coming Up For Air"

I've been diving down
I like this part
Til I startle at the sound
Of my own heart
I need to catch my breath
To avoid uncertain death
But you've found
Another way around
With life support

But I'm coming up for air
I'm coming up for air
I'm coming up for air
But you know how to live down there

Green and grey
Silhouettes and waves
You can stay
But I'm losing track of days
We breathe each other in
I've made it my mission
To go down deep
But there's promises to keep
And nights of restless sleep
That keep me

Coming up for air
Coming up for air
I'm coming up for air
But you know how to live down there
