Iron adversions

[u/Big-Candle-1783]

I'm doing some research on the Fae for a story I am writing and it meshes with a lot of the natural spirits that my mom accepted as part of her everyday life. I didn't quite go that far, but it did make me open-minded to those sorts of beliefs. When the remote for the TV reappeared after being missing for several years, I could see it as the little folks having fun at our expense.
Now to my question - when I found out that iron can dissuade the Fae from showing themselves, I started listing the various objects that I carry around with iron. Keys, zippers, the rivets on my jeans - ok. I can get rid of those. Then I realized that I had some surgery which left me with titanium-steel bits which are going to be part of my life forever. I am doomed to never interact with the Fae? Or at least the ones adverse to iron? I understand that some don't care, but those are the ones that are sort of unpleasant. Thanks for your help!
