blood being frequently described as having a "coppery smell" in fiction is kind of funny considering that there is a metallic component to blood and it's not copper
in fact if your blood smells or tastes like copper you probably have more urgent things to worry about than it being outside your body. it's probably better that it's not inside you anymore actually.
story where blood is described as smelling or tasting "coppery" and it's actually early foreshadowing that all the characters are suffering from heavy metal poisoning
I feel like people smell the iron, think metal and connect it to copper sometimes. But yeah thats... thats not the metal element in your blood lol
When your blood smells like some kind of metal its iron. That's the metal in your blood (well its part of the hemoglobin in your blood). Thats a very important part of your blood tbh, since the iron in hemoglobin helps with oxygen and CO2 transfer.
