I am prompted to revisit this topic after viewing this video of Tada Hiroshi, a remarkable 94 year old aikido instructor. For those who like order, you are in trouble. I will live up to my promise of ‘casual’ – this will go all over the place. I’ve got no final point to arrive at–this essay is more like a jazz improv on a basic theme, the latter of which might have been insipid to begin with. [NOTE: A few people contacted me that they were unable to see the embedded videos, so I’ve also put a direct link under each one.]
