Human Tear Under a Microscope.

Salty water that our tear-duct releases? Yes. However the reason we shed a tear can impact how it looks under a microscope. It was a random comment by Rose-Lynn Fisher's father that got her researching on tears. He wondered is there would be a difference between happy&sad tears. She found the thought intriguing and went ahead to study the different types of tears to see if they were alike on a microscope level. What she found was that there were a 100 different types of tears that we humans shed. She obviously went ahead to categorize them based on different attributes. But what is most interesting about the results is how much they look like Arial View of Earth. Every single thing about the human body is so complicated yet so intriguing. Who knew there could be a map of emotions?
