I’ll start: my ear wax. Several months ago, I observed what I thought to be extra wax coming out of my ears. Since then, I can’t stop trying to keep my ears clean. Wash in the shower with soap every day. Stick my finger in there when nobody’s looking to try to get some out. And so on.
I don’t use q-tips, and I know the advice is to simply let it come out when it wants. But I hate cleaning the gunk off my AirPods! Stupid ear wax, I think I feel some now.
Leave it in there, it keeps out the bugs!
I just read that article about screwworms and how some lady who took a nap on the beach while on vacation had these eggs laid in her ear. You might be on to something.
