The Incredible Diversity of Tears

The Incredible Diversity of Tears

This is amazing. It turns out that, when examined with an electron microscope, tears of grief, sadness, and happiness look profoundly different.

Closely studying tears for so long has made Fisher think of them as far more than a salty liquid we discharge during difficult moments. “Tears are the medium of our most primal language in moments as unrelenting as death, as basic as hunger and as complex as a rite of passage,” she says. “It’s as though each one of our tears carries a microcosm of the collective human experience, like one drop of an ocean.”

Beautiful, haunting, mesmerizing. Skim the whole thing.
