Yes, I always used to think blood had an iron-like smell. What always bothered me the most is the sight of blood, for some reason.
I don't mind blood so much now, however when I go for blood tests, I still stare at the clock so I don't see it going in the needle.
One of the people who work taking blood told my Mom once that on his very first day there he drew blood from someone, asked them if they were doing okay, then promptly passed out!
