Why do mammals have hair in their ears?

Located in the fluid-filled part of the inner ear called the cochlea, these outer hair cells sport tufts of hair-like cilia that project into the fluid. ... The contraction pulls the tufts of cilia downward, which maximizes the force of their vibration. In mammals, both the cilia and the cell itself vibrate.

Tweezing, okay, fine, but only the big ones that stick all the way out of your inner ear. Never stick a tweezer or anything into your actual ear canal. ... And if you so choose to remove the fuzz around your ear itself, we'd still implore you to keep sharp razors and hot wax away from there.
