Who is standing in the middle of these organs trying to balance the see-saw? That is the imaginary Mr Rational on the pivot, and he is a buzz kill.
My heart has taken over my prefrontal cortex. My frontal lobe has selective attention and there is only one thing on my mind. I am out of control and I like it.
And if I break my own heart while I wreck my brain: I will take a full strength Aspirin, wrap myself in sterile gauze, listen to my heart tones and check my pupils.

no point in being rational. after all what can these stellar number of cardiologists do?dont you know that death waits invisibly at the end of the turn?
just do what your heart tells you and live in peace!
It is a dangerous battle for the soul: the heart vs the mind. I am pretty sure they go together, and being rational is not one of my characteristics most times anyway.
