I think...

Human fall in love so easily because we crave things.
We crave the feeling that love brings.
The race of heart, the slight adrenaline.
It's a rush.
I don't think we fall in love so to speak, it's more of an infatuation.
We fall in land when we fall in love with a painting and how the colours swirl and burst.
It brings up emotion we never knew we had.
And when we fall in love with someone. we fall in love with their eyes, lips, fingers, the small crinkles around their eyes when they laugh.
I don't think we fall in love, actual love, with someone until much later.
Until we are done being obsessed.
Our hearts races a little slower, the adrenaline not as strong. But it's still there. Always.
It's no longer crazy ride, though.
It's a strong steady beat.
One that we know and are comfortable with, just like how we had become comfortable with the sound of our hearts beating as one.

Have a good day ahead lovelies.
