The olden days were pretty fun if you liked wearing chainmail or chopping people's heads off but there was one tiny little problem back then - doctors didn't have the slightest clue about how our bodies worked. It's time to find out why Ancient Egyptians thought the brain was just a useless load of old stuffing that might as well be chucked in the bin, why teachers forced their pupils to smoke cigarettes, why hairdressers would cut off their customers' legs, and why people used to get paid for farting. (Unfortunately that's no longer a thing - sorry.) You'll get answers to questions like: Why did patients gargle with wee? How did a doctor save people's lives using a washing machine, a can of beans and some old sausages? What was the great stink? (No, it's not what doctors call your bum).
