Hey Namrata, what a superb question! Loves really does make us all wonder whether it is just “a chemical reaction in your brain” – in the words of Savage Garden or a cultural influence. I personally think a bit of both. Many researches have established that there are certain hormones, chemicals, neurotransmitters affected when a person describes being in love. And as for cultural influence, love hs different connotations in different cultures. Let’s wait and see what others have to say!
