I think this is a different thing but I have a really strong sense of smell. It's a blessing and a curse. I have smelt gas leaks when other people couldn't, mold in hard to find places, not visibly off food. Bin lorries, food waste bags, dog
tit, meat and cheese all make me heave. The smell gets in my nose and down my throat
Jack's cooking would kill me. But I can't smell unusual things like lies or Parkinson's. There are at least two documented women who have that ability. And it is thought some animals like cats a d dogs can smell cancer in humans.
