ELI5: Earwax

why do our bodies make it? What happens if a person never cleans his or her ears? Does eating something make a person have more or less earwax? i want to know everything about earwax. thanks.

There's a lot of sensitive skin in your ear canal, and earwax protects it from bacteria and from drying out.  It's also a good way to get foreign crap out of the ear canal (sort of like how mucus in your nose gets stuff out of your nose) -- imagine a very slow moving river of earwax.

Your ear is designed so that earwax gradually dries up and flakes out, so most of the time, no cleaning is really necessary.
