      Not only does it help from drying out, but it helps with smell too; some things are better detected with a slower airflow

          Two nostrils allows for stereo smells. If we only had one nostril, we would only be able to smell in mono.

          I was going to say because it would be fucking weird if we just had one big nose hole. Now I’m thinking about it, our nostrils are already pretty weird.

          I’m now looking in the mirror at my nostrils and pumping them to the beat of a song.

      Also just to add to the torture of these conversations … the inside of your lungs also have a certain ‘scent’ or ‘aroma’ to it. It’s very subtle and wouldn’t be noticeable to anyone else except for yourself because the exhaled air is coming straight out of your lungs and right past your nostrils and all its receptors. Your receptors can sense it but your brain automatically ignores it and you never notice.

      The same goes for your vision … you have a natural blind spot in the center of your vision … the edges are not crisp and clean, you can only focus on about 10 percent of what you actually see in front of you, the rest is just blurry … your brain just automatically processes your entire vision and autogenerates a perceived image that makes us believe that we have crystal clear vision through our entire field of view.

      Same goes with hearing … just about every person has a tiny bit of tinnitus, ringing of the ears but your brain just automatically processes it all out to make you think that you have crystal clear hearing.

      When you think about it … all our senses are pretty imperfect and there is a lot of interference and nonsense data that our brain processes out to make us believe that we have perfect or near perfect vision, hearing and sense of smell.

        Yes, and most importantly I would say : immune system’s way of cleaning each side…
        The clogging is caused by the swelling (with the blood vessels and the action of blood’s white cells … or … maybe I should read the article again)
