From my lungs to your ears
And then hopefully your brain
The squishy bit in the midfield
That copes with love and pain
The Hypothalamus spreads
Joy and doom through the land
Secreting oxytocin  
From the pituitary gland

Not to be confused
With the hippopotamus
Which controls memory
Short term not bottomless
That might explain
Why we do it again
And again
Walking the line twixst
Love's
Heaven
And
Hell
