Emotion Limits

The conjunctiva's lubricated by tears secreted by the lacrimal/lachrymal or tear gland. The tear gland lies in the outer corner of the upper eyelid. The tears that it produces flow out between the eyelids and the exposed part of the eyeball, helping to reduce friction when the eyelids move. Dust particles entering the eye usually cause greater production of tears which wash them away. Excess tears drain naso-lacrimal/lachrymal duct, which runs from the inner corner of the eye to the nose. Emotion may cause excess tears to be secreted and passed into the naso-lacrimal/lachrymal duct so that one experiences a "running nose" or even overflow, causing "crying".

It's okay for men to burst into tears.
