That's an interesting point about single individuals potentially being happier due to their independence and freedom. However, other research indicates that people in healthy, supportive relationships tend to report higher levels of happiness and life satisfaction. Having a partner can provide emotional support, companionship, and a sense of security, which are significant contributors to overall well-being. Ultimately, happiness is subjective and can vary greatly from person to person. It might be beneficial to look at studies that examine how happiness levels change over time for both single individuals and those in relationships to get a more comprehensive understanding.
