In this episode we talk about the illusion of free will and how the static in the background of your brain might be the only thing separating you from a robot, how the Middle East invaded Neolithic Europe and made the world the way it is today, the dangers and benefits of cannabis, how humans are responsible for something horrible, how punching each other in the face drove human evolution and why one of the most famous ancient temples on earth was covered in graffiti without anyone noticing. All that and we talk about what weird thing men who masturbate too much have in common.
