There are many kinds of love which are induced by a varied collection of motives. Romantic love is probably the most intricate of them all, and there are many reasons for that. First, romantic love does not seem to follow many of our decision-making rules: you can fall in love with anyone, at anytime, and without any precedents. Second, the concept of romantic love has been developed, propagated and nurtured, becoming to some extent intrinsically related to the very meaning of human life. Third, and maybe most important of all, love generates an astounding rush of adrenaline - a rapturous sensation of being out of control, like endeavouring in a great and unique experience.

Love seems to derive from a blend of environmental and genetic factors. Before the scientific study of love originated around the 70s, much of our perspective on the concept was based in the work of poets artists and philosophers. Albeit love remains a complex matter, there are some cues as to why it is such an appealing one.
