Understanding Information Transmission - Anderson, John B

Biographie:
Anderson wrote this book as a simple visual tool to make clear that while appearing normal, living with Chronic Fatigue is a life-changing and controlling disease with a complex combination and fluctuation of symptoms that cannot be seen.

Adjusting to change, letting go of control, focusing on wellbeing, practicing yoga, and simply trusting and accepting what is has been a profound learning experience for Anderson.
