Do you have any reading on this? Both my brother and I lost much of our sense of smell. Him to a far larger extent than me.

Don’t know why, or when. I just know mine is lesser than that of most people based on how soon they smell things or how near.

My brother saw a specialist. I think after trying a few things they recommended smell training which helped a bit. But they didn’t describe it as especially serious, so I’d be curious to know what you’re referring to.

(I don’t mean in a skeptical way, but rather that I don’t know too much about the condition)
