One's never to old, imho, to train in the and continue in training in the MA. I'll be 56 this October and I've been doing Shindokan ever since I was 7 years old. The saying goes..."You're only as old as you feel!" I think this is an honest statement of encouragement for anyone, not just MAists. Are you feeling too old or just out of shape? Either way, age, imho, is what it is and nothing can be done about it. Being out of shape, well, execise is a wonderful thing all across the board. Now...TRAIN your heart out!! I am not feeling too old, little out of shape maybe but at weekend I went to a competition and was placed in veterans category if I honest this was very disheartening once I found out I was the only none black belt in the category....I am 9 kyu so has you can imagine fighting a 5th dan was a little nervy (really enjoyed it though and learnt loads). I think this is what has got me thinking about it not so much the fighting but kata as these guys have had years to perfect them and I have had 4 months. Thanks
