"I have a heightened sense of ____"?

For me, it’s smell. I’m like a bloodhound. Often you’ll hear me saying “do you smell that?”, with someone responding “no”.

Sadly, this sucks at times because if the smell comes off as too strong, I gag. I went into my Dad’s basement whilst slurping some milk out of a mug, last night, and what would be a light musty smell for some, for me, it was overpowering and made me retch.
