I think some folks get confused with whats needed/wanted in general versus whats needed to live & breath.
Let's get this one out of the way 1st- I can breath without an Editor. So can you.
That doesn't however remove the fact that it will be a great tool to have for most of us.
But you're right. It's not needed for inhalation or exhalation from the lungs.
As always, YMMV. Now breath....
