Is one (or more) of your five senses (or 6, as the case may be) more acute than the average person's?

I’ve known people who have better than 20/20 vision—having been legally blind most of my life, I can’t even fathom that! However, I think my hearing is better than most. Did you know the security cameras in department stores emit a very, very high pitched squeal? They do…before the age of about 28 I could hear it! I can’t hear it any more, but even now my hearing is still really good. The other day I was about 20 feet away from my cell phone. It was tucked in a thick pocket of a thick, furry winter coat, behind a pair of gloves——AND it was set to vibrate only….and I heard it go off. It was almost subliminal, but I heard it. My boss, sitting only about 10 feet away from the phone didn’t hear anything. How about you? Is your hearing, smell, sight, anything above average?
