They said that love is similar to a drug. But is it just a drug? That is an argument of Larry Young – professor of neuroscience

at Emory University in Atlanta, Georgia. Professor Young writing in respected scientific journal Nature argues that love can be explained by a series of neuron-chemical reactions in specific areas in our brain. If it is true, he says, people will 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 to others, an antidote to unrequited love.

There is even the prospect of a genetic “love test” to evaluate whether two potential love birds are predisposed to a happy married life.
