How Sains explain Love

I was accidentally found this article:

http://news.id.msn.com/okezone/lifestyle/article.aspx?cp-documentid=3979961

It is written in Indonesian.. haha... I am too lazy to translate it... because it is just full of jargon which I do not know what kind of hormone, enzyme, etc etc.. haha....

For me, Love is just something that cannot be fully understood... hahaha...... It is complicated, un-explainable, un-expected, un-believable, weird, etc etc... Dunno laaa... haha....
