Tears of change
Tears of grief.
Tears from the onion.
Joseph Stromberg, from the Smithsonian’s college of Arts and Science, explained us the secret of the topography of tears. He explained that there are three major types of tears classified as basal, reflex and psychic. Psychic tears are the one triggered by emotions. All these types of tears contain some common substances like antibodies, oils, enzymes and salt.
