Millions of years of evolution have seen fit to bestow me with a ridiculous amount of ear hair.
I feel this is significant in some way — though not socially celebrated (so I bushwack it) — but I have no idea how to use it or what evolutionary advantage it gives me — other than, in its natural state, scare away potential mates.
And that doesn’t seem like an evolutionary advantage at all.
Ear hair! What are you good for? Let your purpose be known!
