You didn't choose most of your behavior. It was left behind.

Instinct Leftovers digs into human evolution, psychology, and anthropology to explain the strange, involuntary things you do every day and traces each one back to the ancient instinct still running the show underneath. Real research, real experiments, told in plain language, always pointed back at your own life.

If you've ever caught yourself doing something and thought "why did I just do that?" this channel is where you'll find the answer.
