Here is a football video that has viral on the net. For good reason, it is clever. As a martial artist I think it shows us the lesson of how aiki works. Don't let the other person's system know you are fighting is the key. If you do an action calm and relaxed it does not trigger alarms in your partners or opponents nervous system.
Lowry Sensei has been using the phrase 'tactile invisibility' lately. I like that phrase.
Confuse your opponents nervous system with relaxed movement.
