Francis Huntrodds and his wife Mary, buried together in Whitby, died within five hours of one another on their 80th birthday - their joint 80th birthday. They were both born on September 19th 1600, and both died on September 19th 1680. And, for completeness, got married on September 19th too.
So September 19th should be Huntrodds' Day, a national celebration of chance and coincidence, says Cambridge University's Winton Professor of the Public Understanding of Risk, David Spiegelhalter.
