Well, I did go and train. A 100 minute round trip, but it was great. I could still remember 80% or more of the Japanese terminology. My form had deteriorated a lot though. And I'm not as flexible as I was.

@HuwEvans Few of us are... I hope that you were kind with yourself during the session and after. One of the truisms I always heard was that most injuries happen after coming back to the practice because your brain still knows how to move that fast and kick that high, but it's often lost the reflexes to keep you from over-straining...
