I knew a guy that died from a nose bleed in the 70s. He was in the hospital for almost a month trying to get it stopped.
I had nosebleeds for a while when I was a kid. I could feel it coming on, a burning sensation, then a slight “pop” then that metallic smell, then the blood pouring out. Didn’t happen more than a couple of times. It was more of an embarrassment than anything else, no thought to it being potentially fatal.
