In my opinion, there are two types of falling in love for human beings, Natural-love and Artificial-Love...

...Hearts can't be matched easily. They're not as flexible as brains. Brains get convinced with logical statements, they are fine for daily decision-makings, but when it comes to more complex issues like Love, a sharper assistant is required. You can't make a fool out of your heart just like you do to your brain, not for a long time. Hearts ONLY get happy with Natural-Love...
