HACHOOOO!

A sneeze (or sternutation) is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic involuntary action resulting chiefly from irritation of the nasal mucous membrane. Sneezing is possibly linked to sudden exposure to bright light, sudden change (fall) in temperature, breeze of cold air, a particularly full stomach, or viral infection, and can lead to the spread of disease. The myth that the speed of a sneeze travels at 100 mph is indeed a myth tested by the Mythbusters, a show on Discovery Channel that "busts" myths.

note: don't ever try to sneeze with your nose, ears and mouth closed cuz then your eyes might pop out!!
