I have a very sensitive nose. This sometimes makes travelling in public transport a problem. Fast food combined with overperfumed people and sweat. 

I remember having business appointments in the morning, shaking hands with men who had just poured aftershave all over them, leaving residue on their hands. I would smell it hours after they left. 

What a blessing is working from home. Although cat litter can sometimes be a bit overwhelming too. I really love those scents you have in saunas: mint, eucalyptus, rosemary. I now one of these aroma diffusers, that distribute essential oil. Would it improve productivity?
