Dr. Bonnie Le, a researcher and author, explores how significant relationship milestones impact our well-being. She reveals that events like marriage, divorce, and childbirth can influence happiness but not always as expected. While marriage might bring a temporary boost in life satisfaction, most people return to baseline levels quite quickly. Surprisingly, breakups tend to hit less hard than anticipated, while bereavement exhibits a stronger, more prolonged effect. Bonnie also shares adaptation strategies to navigate these emotional changes.
