Humans are wired for social connection—our ancestors literally survived because they stuck together. Studies consistently show that people with strong relationships live longer, healthier, and happier lives. While solitude can be beneficial for mental clarity and self-reflection, prolonged isolation often leads to loneliness, stress, and even health problems. Family, friends, and romantic partners provide emotional support, purpose, and joy. Can you be happy alone? Yes, for a while. But for long-term well-being, relationships are key.
