Question

supposing that a tube 5 cm long is fixed to our nostruls and the openings are sealed by vaseline. What will be the effects?​

Answer 1

The upside to having a nose is its faithful ability to detect wondrous aromas. Our nose serves as a sensor, helping us determine if a potential food source is toxic or edible, friend or foe. The nose knows whether it's coffee we're sniffing, spoiled leftovers -- or worse.
