Human beings rely on connections and support from others for their well-being and longevity. Research, such as the Harvard Longevity Study, indicates that having friends leads to a longer life, less anxiety, more peace, and increased happiness.

People desire meaningful friendships, and lacking them can have detrimental effects on both mental and physical health.
