James May at the BBC investigates the science of hangovers in this charming video. With Monty Python-esq graphics and retro-style video clips, May points out that on average we each drink a gallon of pure alcohol a year, which may be contributing to hangover symptoms such as headaches, dizziness, and nausea. He goes on to follow the path of alcohol in your body from that first drink to a hangover that can last up to 24 hours. And those headaches? Apparently your brain shrinks and pulls on the membranes that connect it to your skull, causing the familiar throbbing head sensation.
