The human body is like a collection of aliens. Each organ is alive, uniquely (astonishingly) intelligent, symbiotic with all others and the world… our organs are really like alien pets who comprise us. We are a strange zoo inside. Don’t believe me? Go open your mouth in front of a mirror and observe your tongue as you explore around inside your own mouth with it. Take a few moments and just watch. Tell me again that your tongue isn’t more like a pet alien than an ‘organ’?
