Unusual facts about sneezing
The material spread by sneezing can travel 2-3 metres, at a speed of around 150 km/hour, so it's a very efficient way of spreading germs. Some people sneeze when they pluck their eyebrows, get cold or go out into the sun. "Sun sneezing (Photic sneezing)" often runs in families, and occurs in around one in four people. The world record for sneezing is held by Donna Griffiths from Worstershire in the UK, who sneezed for 978 days in a row, stopping on 16 September 1983 (http://www.guinnessworldrecords.com ). For those with hay fever, it's also very hard to avoid exposure to allergic triggers. Allergen has been found in underwater submarines, in scuba tanks, the Antarctic and even in space! (In space, no one can hear you sneeze?) Some even credit the development of movies to Thomas Edison's serial photos of someone sneezing in 1894.
