This is fascinating. I haven't noticed a change in my ability to smell - it is so far unaffected in my sixth decade of life. But, because I'm diabetic, I avoid refined sugar - I can always tell that sugar levels are high when I get a stuffy nose or snore although that doesn't impede my sense of smell. The nose can indeed tell one a lot. Maintaining healthy habits is hard but much less so than feeling unwell.
