Same here LMO I am beat tonight and soon off to bed though I may touch some of my PM's but it's odd how we both have been thinking about this. Maybe its the seasons about to change. We shall all talk about this soon I am sure someone has had biofeedback with all the members in here. Seems also it could not fail and would greatly reduce stress like breathing I have done to kill the anxiety and slow my heart rate . It helps so imagine being so intune that you have a better handle on the control of these functions. I am so tired I sound crazy sorry
