Dear Friends, I had composed this poem in 2008 after reading an
article by a Lady Doctor who was a Biologist, and had initially posted it on 'Poemhunter.com'. Hope you will like it! Thanks, - Raj

PHYSICS AND CHEMISTRY OF LOVE !
Love’s physics and chemistry, has forever
remained a mystery!
There are no permanent equations to resolve,
Love's unseen wave like force!
It travels through three dimensional space,
At frequencies higher than electromagnetic
waves!
It remains unhindered by barriers of cast, creed,
or clime,
Giving two beating hearts a feel of the divine!
It generates a magnetic force field, making
two hearts in unison beat!
Yet Biologists claim that a chemical called
(PEA) Phenylethylamine, -
Triggers loves molecules in the human mind!
Chocolates are rich in this PEA content they say,
And is a perfect gift on the Valentine’s Day!
The chemical Dopamine makes the lovers to
glow and feel fine,
When they live on love and fresh air and may
even forget to dine!
While Norepinephrine, which stimulates our
adrenaline production,
Makes the lovers world go round in a joyous
motion!
But Oxytoxin that 'cuddling chemical',  requires
constant contact for its effects to prevail!
Cupid’s arrows may be dipped in its pail,
Before those arrows on lovers begin to hail!
Creating unbearable attraction leading to infatuation,
Making two hearts beat as one with love’s magic
potion!
But such feelings remain for a limited duration,
Varying with people with different emotions!
In a 'mercurial type' loves ecstasy gets mixed, -
And they frequently require a PEA fix!
But those who stick to a single mate,
Are said to be rich in Vasopressin content!
And finally when infatuation gradually subsides,
Chemicals triggered by Endorphine slowly overtakes,
When calmness and stability with loving bond
prevails!
This Endorphine is reputed to be rather addictive,
And firmly binds those forces released by PEA, -
which are rather seductive!
