Love And Affection : Way to better feelings

In this book I want to tell my readers that, ....What is love ? And why people fall in love?.And
why are some forms of love so lasting and others
so fleeting?.Psychologists and the reseachers have
proposed several differrent theories of love to
explain how the love forms ?and how the love
endures in the human mind.?
Actuallly the Love is the basic human emotion of
their mind and of their affection which comes
from their emotional thinking of their mind.
But when we go to understand this how and why
it happens is not necessarily easy in this state.In
fact, for a long time, many people suggested that
love was simply something too primal, mysterious
and the spiritual for science to ever fully
understand.
