Why are we so addicted to love?

A study says that falling in love only takes about a fifth of a second.

Does the heart fall in love, or the brain?

"That’s a tricky question always. I would say the brain, but the heart is also related because the complex concept of love is formed by both bottom-up and top-down processes from the brain to the heart and vice versa. For instance, activation in some parts of the brain can generate stimulations to the heart, butterflies in the stomach. Some symptoms we sometimes feel as a manifestation of the heart may sometimes be coming from the brain" says Ortigue.

Love can make you the happiest person on earth or the saddest. Without it, we would be just simple human beings, without any emotions or need to be with someone.

So why we are so addicted to love?

A study says that love has a drug effect to us and scientists have traced the origin of love to a part of the brain linked to drug addiction. It forms a habit out of pleasurable feelings of sexual desire that no-one wants to break. The same mechanism compels the drug addict to keep seeking another "hit" from heroin.

So when we fall in love we actually experiment the same thing like a drug addict!
