You can hear it now. Breathe in through your nose, hold and exhale through your mouth. You are transported to a yoga class of long ago, when we could all gather and exhale in front of each other. Now, transport yourself to a dental chair and hear me saying the same words to you. WHAT? I know, you have probably never had a dentist talk to you about your breathing other than trying to keep you from hyperventilating. Then again, you have clearly never been in my dental chair!
