I have also been anosmic since birth (now 67) and generally never mention it, as most people find it amusing. However listening to your programme was the first time I have heard of the trigeminal nerve; after all this time I now know why I can recognise "mint" and get a tingle from putting my nose in a glass of whisky.
Listeners seemed to really connect with the programme - and learn things, as I did.
Both my daughter and I are anosmic since birth - what a great radio programme! All I would like to do is smell my daughter all she wants to smell is "farts" - oh to be 11. Nice to know we are not alone! Thank you!
You can listen to the programme on the Radio 4 website (or if it's no longer available on my website here.)
