The Ancient Reason You Feel Lonely in a Crowd

For hundreds of thousands of years, being alone was nearly impossible. Our ancestors lived in tight-knit tribes of 30 to 150 people where belonging wasn't scheduled—it was woven into every waking moment. Today, millions of people live, work, and eat completely isolated, yet wonder why loneliness feels so unbearable. In this video, we explore the evolutionary mismatch behind modern disconnection: why your nervous system treats social isolation as a physical survival threat, why social media fails to satisfy our ancient social software, and why we are still searching for the warmth of the tribe.
