Question: How come when somebody sneezes somebody else sneezes too.?
Answers:
When someone sneezes, a gush of respiratory droplets go into the air. These droplets move about 90 mph at a distance of up to 12 feet away. These respiratory droplets are inhaled into another person's nose as a foreign particle (that possibly carries bacteria/viruses that are potentially harmful), so this excites the trigeminal nerve. The trigeminal nerve in the nose sends a signal to the sneezing center in the brain. A signal is sent from the sneezing center to the respiratory center causing a deep inspiration and forceful expiration (a sneeze).
