This reminds me of the video of an old Kiai Master (using chi to physically attack people) fighting a young karate guy. The old guy can't really do anything and gets hit a couple times. It's pretty funny but also pretty sad that the Kiai Master's students led him to believe that he was actually affecting them with his chi attacks, probably over the course of several years. http://www.youtube.com/watch?v=oMgVmFzBrus
