I learned one thing when interviewing surgeons about nose surgery (until the best one explained how really complicated it would be and talked me out of it). The nose and breathing system is seriously complicated. I researched a lot, read studies, and paid very close attention to abysmally-failed nose surgery disasters. But I had no appreciation of all that the nasal passages and nose have to do. The obvious jobs include warming and "dampening" too-dry air. Nasal hairs trap pollutants including bacteria and viruses. And there's an area in the back region that makes antibodies to help kill some of the germs stuff. When covid hit, I used an inexpensive NeilMed nasal lavage daily with the NeilMed salt/baking soda solution after reading that the covid virus was killed by salt in some article. And the covid virus was known to hibernate at the back of the nose/throat so I figured it was worth a try.

I'm a sailor and was interested to read how, in a sense, the nose also balances differential airflow, in part to protect the ear canals. Not the same as trimming sails but the aerodynamics are similar as balancing different forces is what makes it all work.

The ENT who talked me out of surgery and, years later, did the successful Vivaer, was happy to talk with a patient who was impressed with how complicated the while ENT system is and why he still finds it fascinating.
