So far I tried to answer my first question, how our bodies can "know" so much about our situations. It is because bodies are interactions, because much of that is sentient, and because the sentience can also come as an inward datum, a felt sense.

But you speak and act from a sense of the whole situation. That sense guides how you act and what you say, think, and need, in the situation. You would be lost without that bodily sense of the situation.
