Patti A. Wood, an Atlanta-based consultant who created the Achoo IQ Study for Benadryl, said a sneeze could offer a revealing look at someone's personality, reported the online edition of ABC News.
Wood categorised sneezers into four categories: nice, be right, get it done and enthusiastic.
Wood classifies you as a "nice sneezer" if you are a single sneezer and turn away when you do so. People in the category are characterised as being warm, helpful, supportive and nurturing of others.
Or are you the type to let a big loud sneeze out? These sneezers, or "get it done" sneezers, are found to be fast, decisive and to the point. They typically make the best leaders.
Do you always keep tissues handy and cover your mouth when you feel a sneeze coming? These are the "be right" sneezers and are typically the careful, accurate, deep-thinking type, said Wood.
The last group are the enthusiastic sneezers. These are the people with sneezes you notice - such as your grandfather whose sneezes perhaps terrify you, or your co-worker who always sneezes five times.
The enthusiastic sneezers were found to be charismatic and social and have the ability to motivate others.
