Science of Love

They told me that love is a psychic malady that lasts at least four years:
Neurons are firing in your head and cause chemicals react and you get high when the object of your love is near you or when you interact with it in some way. You just keep doing it like a lab rat that keeps pushing the button to get a drop of sweet water.

After 4 years the rat is dead and you move on in search of another object of your love.

It’s a nice explanation, but I wonder how all this begins, how you get infected.
Is it a mimetic desire, a woman with another bloke, that fires the first burst in your brain?
Is it her fluids that seep through her underwear and ignite your receptors?
Or is it her body language that tells you that she is on the heat?

Why one woman sets you on fire while you let another pass without you feel any emotion at all?
Is it because the first one looks like your mother? Or because of the contrary?

May be it is nothing to do with a woman as such, may be it is your instinct of spreading your kind, which tells you that you must find a mate and tricks you and points you to any woman that looks reproductive enough as to your object of love?

But rats in my head keep pushing buttons with memories of you after you’ve gone out of my life years ago and I keep licking those sweet drops like an addict.
