This was an absolutely beautiful, beautiful, beautiful presentation !! So clearly presented. I was just a little curious about cilia in the nose, but I think I have been inspired to learn all that you have explained. I'll also watch some other videos of yours.

Is it possible for the cilia to become permanently damaged to the point where a Non smoking person ends up getting chronic inflammation and infections in the airways? Can damaged cilia be repaired with medication?

Thank's for uploading, i got a big problem where my cilia's don't function anymore. Been trying so hard, with my nebulizer routine, and physio, but still struggling to loosen up the mucus. Surely there's got to be something out there, as this is causing big problem's. The back of my lung's hurt so much, and get a odd pulsing sensation from the lung's.
