In "The Woman Who Stole My Life," Marian Keyes explores the impact of social media on mental health and well-being. One of the striking observations made is the comparison of the brain chemicals released during prolonged use of platforms like Twitter to those generated by cocaine. This suggests a potential addictive quality to social media, where engagement can produce a euphoric effect akin to substance use.

The quote encapsulates a deeper commentary on modern life, highlighting how technology can manipulate our brain chemistry and behavior. As users become increasingly absorbed in their online interactions, they may not realize the psychological toll it can take, reflecting a broader concern about the relationship between digital engagement and mental health in contemporary society.
