What physical sensations contribute to the overall feeling of comfort?

what advantage would having the high ground give in a swordfight UNLESS

Sit for a moment and enjoy the felt sense of feeling comfortable.
I attach the word “gladness,” feeling a calm, soft, pulsing flow into my arms and
legs and I am glad (i.e., I have the felt sense of gladness).
I attach the word.
