Hi special smellers! I have been the 'freak' in my family all my life. I can smell anything and everything, even in the next room. These are not 'imagined' smells. They are real. Horrid type smells stay in my brain for at least 24 hours. Since diagnosed with Bronchiectasis 15 years ago I continue to 'smell everything'. It's gotten to the point I don't even mention it if I smell anything like a 'funky drain' etc. around the house, as I live with a denier. The smell is there as when I've investigated any smells, there is a reason. However, I continue to be very sensitive to chemical smells, some perfumes, exhaust etc. I've had MAC, Pseudo and Covid twice, etc. and for me, this special ability to smell things is still with me.
