My mom lost her sense of smell over the course of several years, when she was in her forties. I’m 30 now, and although I still can smell OK, I’m aware that scents are not as strong in my nostrils as they were, say, 10 years ago. Could the propensity to lose one’s sense of smell be hereditary?
Also, my mother claims she doesn't suffer any lack in the taste department, but I've heard that taste and smell are related and that when one loses the ability to smell, the sense of taste often goes with it. I know someone for whom this is true -- he can't smell or taste. Anyone got any ideas/facts about this?
