In the book "Why We Love: The Nature and Chemistry of Romantic Love," Helen Fisher explores the concept of love as an instinctual and unavoidable experience. She suggests that falling in love isn't something people consciously decide to do; rather, it forcibly occurs, almost as if it's beyond our control. This perspective emphasizes the powerful and spontaneous nature of romantic feelings, highlighting that love can overwhelm our emotions and rational thinking.

Fisher's insights reveal that love is deeply rooted in human biology and chemistry, suggesting a complex interplay of neurotransmitters that drive attraction and connection between partners. By framing love as an unexpected phenomenon, she encourages readers to consider the profound impact love has on their lives and how it can shape relationships, sometimes leading to intense devotion or heartache.
