Ive chosen a life that is moderate to highly stimulating on the sympathetic nervous system. Due to loud noises, physical exertion, social dynamics and even the small yet significant stresses of driving to and from work, my sympathetic nervous system is dominating. This results in high cortisol and adrenaline, and reduced production of there homeynes that contribute towards essential bodily functions such as regeneration. To counter this, I dedicate the majority of my free time to activities that bring me all the way back to equilibrium. Nature the colour green, yoga/meditation (sometimes simply watching the world go by) and Music like this, all works wonders.
I also love this Diagram from the CHEK institute demonstrating the 2 essential life forces that contribute to the advancement of novelty.
