It’s sometimes hard to know which parts of the human body serve a purpose and which parts don’t. Sometimes it’s obvious–feet and fingers are important, while evolutionary remnants like the appendix aren’t. Thumbs are an absolute necessity, while we could quite easily live without earlobes.
The purpose of some parts of the body, though, is a little less clear. Are they really contributing to our overall health and welfare, or are they just another bothersome area to scrub in the shower? These four body parts may seem trivial, but without them, things just wouldn’t be the same.
The Eyelashes Grab It
We may think of long, lush eyelashes as signs only of fertility and attractiveness, but they are important for eye health, too. Lashes trap debris and dirt, preventing it from coming in contact with our eyes, which could cause injuries. Eyelashes’ roots also have connections to nerve endings, and a foreign object brushing up against the lashes can trigger a neurological reflex to close the eye, keeping it protected. Even though eyelashes serve an important purpose, however, people can live without them. The size and thickness of lashes vary widely among people, and those with certain forms of alopecia or who are undergoing chemotherapy often have no lashes at all. Although these people don’t suffer from any seriously debilitating effects, they do have to work a little harder to protect their eyes from irritants. For most people, the lack of eyelashes is more a cosmetic concern than a medical one, and many resort to false lashes or lash-enhancing medications and procedures.
