Best way to assess breath of someone : laying on the back, witness the flow of the breath, see how deeply they breath down to their pelvis and how deeply can breathe into that area both consciously and unconsciously.
Observe how deeply breath in their roots and stomach -> assessment both in their daily life and sleep how breath is moving into that place.
Impact ++ of breathing on health -> breathing between 20000 and 26000 times / day (depending on the rhythm and plastic breath pattern or each).
If unconscious breath shallow or not full or tension that hardwaired your plastic? Into that area -> in the 8 hours of sleep, no breath in the abdomen -> no physical massage, no flow, no chi moving into larger intestine -> impact excretion of waste. //
