You may or may not agree with what I say or how I say it. You may not believe it, or perhaps you may find exceptions. But, on a small scale, this is what I and others have observed. I do not think that one is relaxed, centered, or weight-underside at such times.

I think Harry Eto Sensei also did a similar demo at the 1995 Maryland seminar. You may demonstrate these for yourself if you already know the basics of ki testing. As a note, these demonstrations have not been subjected to rigorous scientific testing. However, it would be interesting to do these tests at some point. A great person, with a friendly smile, someone good to know, and an excellent friend.
