The truth will set you free. It will also keep you healthy.
The longer humans remain on earth, the more we will learn about ourselves - individually and globally. These learnings will change us. This is real growth.
Tools exist to enable this self-discovery. However they are restricted and not universally available. Eventually tools will not be required or at be least more accessible. Everyone will know themselves - eventually.
Physically, mentally and spiritually.
The more we truly know about ourselves - the better we can manage ourselves. Consciously and Unconsciously.
This includes managing our health - mentally and physically.
Prevention is better than cure.
