The answer lies in the nature of the sense of smell. Your smell receptors in your olfactory bulb, which resides in your nasal canal, are very sensitive. But you wouldn’t want to smell every smell all the time; you just want to smell new smells. So your smell receptors turn themselves off when an odor persists. That can be bad news when it comes to your breath. It’s just too persistent in your life!
