I am fascinated by tears. Do you know that there are three chemical components of tears?
The first ingredient is salt. The saline content of tears is roughly the equivalent of the salt water in the ocean.
The second ingredient is made up of a combination of vitamins, minerals, and oils which bathe the cornea and keep the eye moist.
And the third chemical component of tears is natural antibiotics that keep the eye germ free.
Now here is the most interesting thing about tears. The chemical substance of our tears change based on why the tears flow. When we weep because of deep hurt or traumatic loss, the chemical substance of our tears change so they become a natural pain killer.
In other words, when we weep because we are in pain, our body tries to sooth us. As the Good Book says, "We are fearfully and wonderfully made."
