Think about when you go to your doctor—they check your blood pressure, they ask if you have any anxiety, they ask maybe about your sexual performance, they ask you about migraines, but they don't ever talk to you about your breathing. They don't look at your levels of O2 or CO2. But breathing is the anchor to so many of those issues. And if you fix your breathing... you can really blunt the symptoms, or in some extraordinary cases, heal yourself of those chronic problems.
