I have a terrible sense of smell at the moment. I don’t know when it happened, but it went slowly and I now have very little. I know that when my wee one was young, and I was changing her nappies, I still had a good sense of smell. Maybe too good. I now have little. I still enjoy food, still enjoy wine. It is probably dulled, but I can still seem to tell (by A/B testing) if a bottle is ‘off’. Though thankly I’ve had very few off bottles, thank goodness. I believe one can train one’s sense of smell and please be careful to be deterministic. We are changing our models of the brain quite a lot and learning that connections can be built again (neuroplasticity). Really, I’m no expert but I know there’s still a lot unknown about the brain.
Certainly, a lack of the sense of smell isn’t help enjoy me cheap supermarket plonk any more - the Wine Society has ruined me!
