New research being done on human saliva suggests some our physical and even personality traits are on display in our spit.

The ongoing research by clinical psychologists at the University of New Orleans shows a vial of human saliva can reveal everything from stress levels, to a person's tendencies in forming relationships.

Specific chemical levels in saliva can also be used to measure the likelihood of a young person developing acne or other skin conditions.
