MRSD, I think I have that weird 'flemen' thing. (Yes, I know that isn't possible unless some ancestor successfully crossed with a cat...eww....let's not go there)
I can smell and taste anything way before any one else has a clue. They could not fit me with a mask for TB cases and told me if I had to work with one, I had to wear one of those huge biohazzard hoods. Thankfully, I retired prior to that. I would have scared the patient to death, and likely suffocated myself in the process.
It's either 'flemen' or ESP by smell.
