Stupid typo - 'no effect'.....
Professor Young argues that love can be explained by a series of neurochemical events that are happening in specific brain areas. If that is true then, he says, one would no longer have to rely on oysters or chocolates to create a loving mood. Instead, it will be possible for scientists to develop aphrodisiacs — chemicals that would make people fall in love with the first person they see. And for those who have fallen in love with someone they shouldn't have fallen in love with, an antidote to unrequited love. There is even the prospect of a genetic "love test" to assess whether two potential love birds are predisposed to a happy married life.
Are we headed towards our very own real-life love potions? Or is there something deeper going on in true love?
I bet the human brain is a kludge. -- Marvin Minsky
