The 'Mary Poppins' Cancer

In this episode of Disappearing Spoon, Sam Kean discusses the horrors of a particular genetic disease that was, literally, sweeping through London in the 1700s. In 1666, the Great Fire of London consumed about 13,000 homes and caused the modern equivalent about $1.3 billion in damage. After the Great Fire, London officials made chimneys mandatory in all homes and buildings. All these new chimneys meant there was a big demand for sweepers. Who did they employ to clean these narrow, soot-filled chimneys you ask? Very young boys.
