What is happening to me?
I have a fever
But at the same time
I feel fine
I am a scientist
Not a believer
Why do I feel like
I’ve been drinking wine
According to my medical history
It started when I met Miss Marie
I must dig deep in my chart
What is happening in my heart?

It’s the chemistry of love
It is sent from above
It’s a gift from the brain
It is running through my veins now so
Itty-bitty pretty peptides
I want to have a lot of
Nice neurotransmitters
It’s the chemistry of love

Dopamine is released
By my neurons
It makes me happy
Makes me feel good
Norepinephrine
Is another hormone
It makes me tremble, blush and sweat
More than I should
But my serotonin is slowly heading down
Making me focus on only the one
Oxytocin is released when we caress
And the sex hormones make us want to undress

It’s the chemistry of love (The chemistry of love)
It is sent from above (Central nervous system)
It’s a gift from the brain (The ventral tegmental area)
It is running through my veins (The arteries and veins)
Itty-bitty pretty peptides (Small, small proteins)
I want to have a lot of (High concentrations)
Nice neurotransmitters (Connecting to receptors)
It’s the chemistry of love (Pure love)

But there is a catch, a love limitation
Unlike the stars up above
Receptors are prone to down-regulation
You can’t be forever in love

It’s the chemistry of love (Oh baby, it’s love)
It is sent from above (Straight from heaven)
It’s a gift from the brain (The muscle of love)
It is running through my veins (It’s pumping, it’s pumping)
Itty-bitty pretty peptides (The size doesn’t matter)
I want to have a lot of (Give me. I can take it)
Nice neurotransmitters (Those sexy synapses)
It’s the chemistry of love (It’s true love)

Chemistry of love. Sent from above. Running through my veins (Love juice in the system)
Chemistry of love. Sent from above (Those marvellous molecules)
Chemistry of love. Sent from above. Running through my veins (Marie, you are toxic)
Chemistry of love. Sent from above (And I love it)
