I recently moved to a new town. While visiting, my mom -- who has a particularly good sense of smell -- noted a constant foulness in the air that I've been unable to pick up on. Clearly, having such an heightened sense of smell can be both a blessing and a curse.
I'm struggling to come up with an adjective that concisely describes this situation. In general, I would call this a "good nose," "sensitive nose," or even "astute nose." None of these quite grasp the light, but empathic tone I'm looking for.
Is there an adjective out there that fits?
Bonus points to whoever can up with a contrasting adjective for my comparatively stunted sense of smell.
