Chapters

If you're breathing through your mouth, sometimes, that's appropriate. If you're sprinting, that's appropriate. If you're exerting yourself, that's appropriate. If you're talking, then that's appropriate. But if you're just sitting there checking email, that's not appropriate. If you're sleeping, it's not appropriate. If you're watching a movie, it's not appropriate. We should be breathing through our nose 95 to 99% of the time. And there are times where you want to be breathing through your mouth and that's appropriate. But for the most part, that's one thing that if you did that, your entire life would change, and I promise you that.
