Do You Have a Threshold?

When a person just passed the threshold, they do breathe faster. They might go from 34 to 38 or forty, but they don't maintain depth. So that's where this over or past threshold piece, the title, volume usually takes a hit because the person can't forcefully breathe out enough. And it becomes on issue over time, especially when you're looking at two, three, four hour events. That ability to move the volume easily as it's going to pay off, i think. I think.
