Absolutely, the super-smeller -- it's horrible. I've heard that the sense of taste is some very high percentage just a sense of smell, but I'm not sure; if my tastebuds are any keener than those of others, it's not by much... or maybe it's the 39 yrs of smoke poisoning... which didn't affect my sense of smell *too* much; even when I smoked a couple pks a day, I could smell things that most other people assured me I was hallucinating... but I never was.
On the other hand, even as a very young child I loved strongly-flavored foods that others hated -- I loved broccoli since I was old enough to beg my mom to buy me "trees," and even Brussels Sprouts... and those nutritional shakes like Ensure... I've always found them extremely appealing, and when I opened a bottle of B Complex vitamins, I understood that what I had been smelling from those shakes was the B vitamin enrichment.
But as I said, I had an ungodly sense of smell even when my head was perpetually wreathed in smoke; road tar seems like what Hell must actually smell like -- now, I will drive 10 miles out of my way to avoid it. And pretty much ALL disinfectants give me a sensation in my nose like I've just inhaled gasoline and snorted a lit match -- many perfumes cause me that same discomfort. But the smells of real roses and gardenias... makes me want to climb inside them and just live there.
But my sense of taste seems fairly normal. My other super-keen sense is actually hearing -- I get accused of hallucinating sounds, too... but I never am.
And I can correctly identify any voice I've ever heard before, within just a few seconds.
