Very sensible of you, Ed. I have no interest in the boxing ring now either. I did teach Tai Chi for a while and still practice regularly. I find the principle of Ying and Yang helps in all walks of life. The harder people push the more likely they are to find that they are pushing at nothing and end up flat on their face :-)

I was interested in Aikido for a while as well but it got a bit too physical for my old bones. I got to like it when someone explained it was the principle of not being where you were expected to be or doing what you were expected to do. I suppose I have mastered the art at work at least...
