So what is it that makes you like someone, fall for him, and not for somebody else, even though the next person may have similar qualities, even meet your expectations, look the way you like? What is this indefinable ingredient in any equation that constitutes love between two people? Or sexual attraction? Pheromones? What makes your heart miss a beat, makes you weak around the knees, gives you butterflies in your tummy, puts a dreamy smile on your face when you think of him or only hear his name mentioned? This x-factor called chemistry?
I had done some research when I first started to talk about it as a self-appointed matchmaker advising clients: the so-called chemistry of love seemed to be just that –– chemical chain reactions in the brain. Researchers even identified a specific chemical in the brain (called phenylethylamine or PEA) believed to be implicated in the thrill and general euphoria that comes with falling in love. PEA is a built-in "love drug." It has stimulant properties like cocaine and amphetamine. Levels of the chemical appear to rise with feelings of infatuation, which, in turn, boosts euphoria and excitement.
