Day 123 - Sigh and Yawn August 31 2015

I can get a serious attack of sighing and/or yawning going. If I am fatigued, stressed, or during and after exercise, one will hit me. Can you read this without yawning? I have struggled with this for many years and it appears that my breath is too shallow most of the time. My brain is wanting more oxygen and desires to get rid of the carbon dioxide building up. Whatever I can do to increase oxygen to my brain, then I am game! Time to learn to breathe.
