A post on my Facebook group which asked this question :
Here’s a question. How do YOU feel, describe, express ENERGY?
I’ve pondered this great question.
I feel energy mostly with my whole body i.e. cold, warmth, discomfort, pain, full of energy etc. My eyes are my signals when I get tired and emotionally drained i.e. red-sore eyes. My lips when I’ve eaten bad spicy food. 
I express energy with my emotional signals/sounds or outburst of happiness, anger, frustration, sadness, pain, agony with words, speeches, sleeplessness, bingeing/craving for food/chocolates.
Mostly I find that if I express my energy outwardly, my energy level goes down and to recharge I have to go inward (which I do often).
Jin Shin Jyutsu helps me to be sensitive or to be aware of my body energy which really helps me to be in touch with my whole being.
