can a person die while sneezing? why do we say " god bless you " after a person sneezes?

It was believed, a long time ago, that the heart stopped beating when one sneezed. Some people thought the soul could be thrown out of the body while sneezing, others thought a person was prone to evil spirits when he sneezed. 'God bless you' was a blessing to shield a person from any harm. It is just a belief that has been passed on and has become part of the common use of language.
