Love is a Sickness

Some psychologists says that they will find cure of sickness of love in next years! They think Love is  a kind of sickness and it can be healed. I just wonder that if love would be healed one day, whether people would be afraid of to be loved or not any more?! Also I wonder another thing; how would they define the love, still people do not know which is love!
Listen ; You have broken my heart!
