Oldest Fear Of Human Kind

You flip a switch and never think twice about it. But for 99.9% of human history, that switch didn't exist — and your brain still hasn't caught up. In this video, you'll discover why darkness feels so different from every other fear you carry, what lions in Tanzania reveal about moonlight and danger, why your brain would rather scream at a coat on a door than miss a real threat, and how the same ancient alarm system still fires when you lie awake at 3am. You'll see how researchers like Craig Packer, Martin Seligman, and Christian Grillon uncovered the science behind it, and why your ancestors' oldest survival tool is still running quietly inside you today.
