This AskMe question revealed something surprising: the commonplace that ears and noses continue to grow has been so little examined that the medical literature on the subject is scarcely enough to assert that it happens at all, let alone why.

And the same goes for why older men grow more hair in their ears and noses.

The tragus is the pointy projection on the front side of your ear opening. Interestingly, tragus can also mean any of the hairs growing at the entrance to the ear. So I guess what you’ve got there, Ernest, is a bad case of tragus on the tragus.

I hadn’t know that tragus could have two meanings. The OED lists only the ear-part definition, not the hairy one.
