Good point, and a valid question.

What I am describing is one of many of the properties of water, not the water itself.

You are correct in implying this as irrelevant based on a human body developing 100 PSI within his body or blood.

The fact water has this capability, is the analogy.

Another analogy is mercury; it flows with the density of bullets (lead), and packs a punch while being fluid.

Mercury is highly conductive, and sensitive to pressure; and wreck havoc even in small amounts electrically and toxicity.

Oh now, now his is saying Qi is mercury; ha, ha.

No, this is an analogy.

If I use the wind as an analogy
for an unseen force of Nature,
and then someone bottles the wind and says;
'this is not Nature':

I will agree.
