That's interesting - didn't know that
I remember the term 'nose-blind' so just looked it up after reading this thread.
''Nose-blindness, or sensory adaptation, is a real thing and there is a reason why it exists. If the brain decides a smell is not a threat [after repeated exposure to it] you don't need to waste any more energy on it, and your nose's odour receptors switch off to it.''
Anyway, I've always liked Fahrenheit.
