I lost my sense of smell in an accident 30 years ago.
I would be SO happy to smell a wet dog or sweaty horse again.
People complain about the piddliest things without ever thinking what it would be like to lose them.
One of my friends lost an eye and her sense of smell (long story) to cancer about 5 years ago. Your sense of smell is something I had never considered to be very important but I was wrong, it is terrible to lose it.
