In the late nineties of the last century, I spent a lot of time among the fisherfolk of India and some other countries. I visited many fishing villages and one significant facet of any Indian fishing village is the drying of fish and prawns during sunny days. The villages would welcome one with the smell of dried fish and it took some time for me to get used to that. Different but strong smells on fishing boats as well had to be learned to endure.
In many of my visits to fisherfolk in Maharashtra and Gujarat I used to be accompanied by a veteran in the business who had spent over three decades in the business. He was blessed with total lack of the sense of smell and I used to think that it was a blessing and wondered if he really did not have the sense or he was just bluffing. Now I realise, after all these years, that there could be a condition called Anosmia!
There must surely be other businesses where Anosmia will be a blessing to be born with! Can you think of some?
While you are thinking of an answer, here is something more on the subject that will be of interest.
