Secret Lifesavers
The doctors demonstrate how our body movements are controlled by confusing their own brains. Dr Chris lets a blood-sucking leech feed on his arm and Dr Xand goes on call with an emergency ambulance team. Meanwhile, over in accident and emergency, a patient has locked their jaw wide open and another needs stitches after a particularly nasty fall.
