For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
I thought my significant other was one of these to a certain extent. It does weird things to me as a DJ. Turns out that she just likes the limited music that she likes and cannot stand most everything else.
that just makes it easier to make a playlist with all their favorite songs.
