Depending on which side you take, this scientist is either your hero or the scrooge of humanity. An American scientist says that true love does not require a Valentine's Day gift as a reward. Say what?

At the risk of being public enemy #1 of all women (and all florists) in the world, a Yale professor tells us that in the face of true love, the reward parts of our brain will be deactivated, according to his research.

"When we truly, selflessly wish for the well-being of others, we’re not getting that same rush of excitement that comes with, say, a tweet from our romantic love interest, because it’s not about us at all," said Judson Brewer, former adjunct professor of psychiatry at Yale and current professor at the University of Massachusetts.

To differentiate from romantic love, Brewer says true love is selfless love, and it's a "deep and genuine wish for the happiness of others without expectation of reward." The selfless act of helping others is a reward in itself. In other words, the (about to be most hated) professor is saying it is not necessary to receive or give those worthless flowers and chocolates on Valentine's Day, if you truly love each other.

But, Professor Brewer, there is only one Mother Teresa and one Dalai Lama who selflessly love humankind. The rest of us Earthlings recognize the need to save people, but can we not savor a little happiness from a simple box of chocolates or a single stem of rose?
