When you sneeze how fast

Some coughs are to clear your airways quickly, but a chronic cough could be a sign of something more serious. Both a sneeze and a cough have one goal in mind: getting rid of whatever is bugging your body. Unfortunately, getting rid of germs in such a violent method means spreading germs in a rather large spray of saliva, mucus, irritants and caught viruses which can live on surfaces for hours at a time.
