My mother's sister also had this sense of smell. My mother told me once that she was on a bus with her sister, when she said "someone on this bus is going to die today." There is no way of knowing if it happened, but it must have happened before as neither one questioned the statement. This aunt of mine wanted to be a nurse, but back then if you got married, you couldn't be in nursing school (before WWII). So, she dropped out. I never inherited this sense of death-I have chronic sinusitis and a poor smell to go with it.
