As Valentine's Day is celebrated worldwide, the article raises a thought-provoking question about the nature of love: Do we truly love the same person we did 10 minutes ago? The piece points to scientific research that shows the human body undergoes continuous changes, with most cells having a lifespan of 7-10 years. This transformation raises the profound question of whether love remains the same as our physical selves evolve.

The article explains that our bodies function as living machines, routinely repairing and regenerating cells. Notably, researchers from Sweden's Karolinska Institute utilized carbon-14 dating to measure the age of various cells in the body, revealing that different organs renew at varying rates. For instance, cells in the gut and intestine have a considerably shorter renewal cycle, potentially indicating that our very essence—our biological makeup—changes over time.

In essence, love could be seen as a chemical reaction influenced by our evolving biology. The article argues that while love may feel everlasting in the moment, it is essential to acknowledge the constant changes within ourselves and consider if love, too, adapts and transforms as we do.
