Last night as I was lying on my bed about to sleep, a violent urge to sneeze seized me, and I was forced to yield to it by letting loose an extremely powerful sneeze. The force of the sneeze threw me up into a sitting position.
This got me thinking: why do we throw our upper body forward when we sneeze? Obviously the sneeze is gas + liquid expelled forward, so by the laws of motion our body should be thrown backward by the reaction instead of forward. When a rocket expels hot gas in one way it flies the other, so our body should behave the same way as well.
Why is that not so?
