Humans’ dry tears have a different chemical makeup

    1. This isn’t really true. Sure, there are different metabolites in different tears, but if you hav two samples of the tame tear they will produce different crystalline structures.

    2. How do tears look like when your life long loving partner tells you they wanna change their gender, but they’ll still love you no matter what, while you’re chopping onions for dinner?

      To be clear, this is less to do with what caused the tears and more about the conditions under which they dried. Per [a Smithsonian article](https://www.smithsonianmag.com/science-nature/the-microscopic-structures-of-dried-human-tears-180947766/) that OP mentions in a comment, but doesn’t provide in their original post:

      > because the structures seen under the microscope are largely crystallized salt, the circumstances under which the tear dries can lead to radically dissimilar shapes and formations, so two psychic tears with the exact same chemical makeup can look very different up close. “There are so many variables—there’s the chemistry, the viscosity, the setting, the evaporation rate and the settings of the microscope,” Fisher says.

    4. Title doesnt rly match the picture.
      U should rly add text and not just title.
      U show 3 times the same chemical Makeup of tears without the fact, that the environment in which the tears dried can make a tremendous different.

      Other than fact actually a cool fact. Thanks for your post!

    5. Tears of change is what my priest said about what happened to my rectum after the first time.

    6. That title in combination with the pictures is kinda misleading since every tear looks different because how salt crystalises.

      While it is true that some tears included stuff like hormones which others do not, that is not what you see in the picture.
