vulnerability of the vital points in relation to the time of day (as described in Bubishi).
Has anybody researched this or heard of any writeups? I'm curious if there is at least some evidence of the validity of this in a modern study.
I have no idea, but my intuition tells me that body is on it's own clock that does not necessaraly correspond to the rising and falling of the sun. For instance, if someone works night shift and sleeps during the day, would the same principals described in Bubishi still hold water?
also, I would think climate and environment adaptation would be factors. or would it make a difference at all?
Thanks in advance for your thoughts.
