too much phenylethylamine

Love, like all things bound to the universe, is non-existent without some amount of physics and chemistry attached to it. As a scientist cynically pointed out, cupid's arrows would never have been effective if they had not been first dipped in one unromantically named chemical- phenylethylamine.

Nor would the human body's reaction have given us dramas like Romeo and Juliet, if oxytocin did not have its way. Together these two form the chemistry of love.The common symptoms of love, including sweaty palms, shaky knees and general restlessness, are caused by a natural chemical, Phenylethylamine (commonly dubbed the `love molecule'). Its release from the brain can be triggered from deceptively simple actions like the meeting of the eyes or touching of the hands. Heady emotions, racing pulses and heavy breathing results, and all these are (unfortunately) clinically explained as an overdose of this chemical.

The latest discovery is the arrangement of molecules in this chemical, the whole world is excited because now, like the witches of the yore, we can actually concoct love potions. In other words, mankind could be on its way to isolating the chemical compound and making drugs that can induce these reactions in us, in other words....you take the drug, and you fall in love with the next person you see.
Speculations all. In truth, all we know about love is still largely out of our control. For instance, infatuation. This is supposedly the first stage of falling in love, an unbearable attraction towards someone. This attraction causes a virtual explosion of nuerochemicals very similar to adrenalin. Assisted by Phenylethylamine (that speeds up the flow of information between cells), dopamine ( that makes us glow and feel good), and norepinephrine (that stimulates the production of adrenalin), make our world go round, our eyes sparkle and our heart beat faster.
Our entire existence then depends on the sight of the person who triggered these reactions to begin with, and as the addiction to the chemical grows stronger, our attraction becomes greater. At this stage we commit foolish mistakes which are the stuff puppy love stories are made of.
Actually it is these three chemicals that combine to give us what we call infatuation. We feel we are energized, often floating on air...and the reason why people who are just falling in love can talk for hours on end... (the same person becomes boring at a later stage)

We can blame our chemicals for everything.We had a list of attributes ready for matching, but we just end up falling in love with the person who possesses none of them...it is , as they say, chemistry. S
ocial obligations, other relationships, sense and sensibility, all take a back seat; our mind soars with these natural drugs.No wonder, a lover and a madman are said to be alike.Scientists also opine that this `clicking' would be with a person with whom we can identify a parent-child situation. A person who, in our subconscious, will give us back something we feel we lost during our growing up years. For some it is security, for some others, it is warmth, and then others, just a spirit of adventure. This could be the reason why demure, well brought up girls usually fall for wastrels.
This subconscious selection of mate gets our phenylethylamines and other chemicals moving. This period when our brain is awash with the love hormones lasts for different durations in different people, between six months to three years. In most of us, it settles down after that.

For mercurial people, this high is missed and that's the reason why they need another temporary high....another relationship, another chemical fix.

If these love junkies stay married, they will need new relationships to keep their dope, and sometimes, bigger highs. hence bigger risks. In this world of chemical signals, humans are not scientifically considered monogamous; we do not fall under the 3% of the species that are monogamous.

Another interesting chemical is oxytoxin, the `cuddling' chemical. It promotes the need to be physically held, have close contact with he mate and makes both the sexes more caring. It can be released simply by a lover's look, smell or even a fantasy.

So much for the chemistry of infatuation.When infatuation subsides, another chemical takes over, which is responsible for intimate relationships. These chemicals are created by endorphins. They make a relationship steadier, intimate, dependable, warm and a great sharing experience. They do not induce a giddy high, but calmness and stability...(Yawn)
